Custom Fillable Number Boxes for Milestone Celebrations
Milestone birthdays and anniversaries deserve packaging that matches the magnitude of the occasion.

Materials for Fillable Number Gift Boxes
A number box needs to hold its shape, support the weight of its contents, and look spectacular. Material selection is critical to achieving all three. Teal Packaging uses substrates engineered for structural integrity and premium print quality.
- E-flute corrugated board (1.5mm): The most popular substrate for custom fillable number boxes. Lightweight yet rigid, able to hold considerable contents weight while maintaining crisp numeral edges and clean fold lines.
- Rigid chipboard (1200gsm-1600gsm): Premium option for number boxes intended for high-end gifting or florist arrangements. Heavier and more substantial but also more durable and luxurious in presentation.
- Coated duplex board (400gsm-500gsm): Mid-weight option offering a smooth white printing surface and sufficient rigidity for lighter content fills.
- Kraft paperboard (400gsm): Natural aesthetic option for rustic or vintage-themed milestone gifting brands.
All constructions include a removable lid section matching the number shape, allowing easy filling of contents after box assembly. Internal dividers can be added for taller boxes holding flowers or balloon arrangements that require compartmented support.
Customization for Custom Number Gift Boxes
Custom fillable number boxes are a highly visual product and their commercial appeal depends significantly on presentation quality. Teal Packaging offers the full range of print and finish options needed to create number boxes that stand out in social media feeds and retail environments.
- Full CMYK and Pantone printing: Vivid, accurate color reproduction for brand colors, event themes, age-specific palettes, and decorative patterns.
- Matte lamination: Sophisticated, soft finish that photographs beautifully and feels premium in the hand.
- Gloss lamination: High-shine surface for bold, celebratory aesthetics.
- Foil stamping (gold, silver, rose gold, holographic): Metallic accents on numerals, border elements, brand names, or decorative patterns. Extremely popular for premium number boxes.
- Spot UV: Gloss highlights on specific elements against a matte background for added visual depth.
- Holographic film: Prismatic holographic effects that catch light dramatically, ideal for limited-edition or ultra-premium number box products.
- Glitter and metallic surface coatings: Full-surface glitter or metallic effects for maximally festive presentations.
- Interior color printing: Print the inside surfaces of the number box with colors, patterns, or messages revealed when the lid is lifted.
- Custom number combinations: Any single digit 0-9 plus double-digit combinations for milestone ages and years.
Free design support is included. Our design team will develop a dieline for your chosen numeral or number combination and apply your artwork accurately across all exterior surfaces.
Size Options for Fillable Number Boxes
Number boxes are available in a range of standard heights to accommodate different content volumes and presentation contexts. Sizes are stated as approximate numeral height x depth (depth being the internal fill space) in inches.
- Small number box: 8 inches tall x 3 inches deep (ideal for candy, small gifts, and confetti fills)
- Medium number box: 12 inches tall x 4 inches deep (the most popular format, suitable for balloon stuffing, candy, and small flowers)
- Large number box: 16 inches tall x 5 inches deep (statement piece format for flowers, large balloon arrangements, and substantial gift fills)
- Extra-large number box: 20 inches tall x 6 inches deep (event centerpiece scale, suitable for large floral arrangements or multiple gift items)
- Custom dimensions: Any height and depth specification tailored to your product offering or event requirements.
Number combination boxes (for ages like 18, 21, 30, 40, 50, 60) are produced as two separate numeral boxes packaged together or as a connected two-digit format, depending on your preference and intended display arrangement.
Sustainability in Custom Number Box Production
Teal Packaging's custom fillable number boxes are produced with FSC-certified board substrates, ensuring the paper and corrugated materials used come from responsibly managed forests. Soy-based inks are used throughout production, reducing environmental impact compared to petroleum-based ink systems. For related packaging needs, explore our CBD boxes.
All board substrates used in number box production are recyclable. Corrugated and chipboard number boxes can be broken down flat and recycled through standard curbside collection in most markets. For brands wishing to communicate sustainability credentials to their customers, FSC certification marks and recyclability symbols can be incorporated into your box design.
The reusable nature of fillable number boxes also contributes to their sustainability credentials. Many recipients reuse number boxes as decorative storage, planter containers, or display items long after the celebration, extending the useful life of the packaging beyond a single event. Explore our custom gift boxes for complementary gifting formats, and our custom rigid boxes for premium keepsake gift presentations alongside your number box range.

Frequently Asked Questions About Custom Fillable Number Boxes
What can I put inside a fillable number box?
bespoke fillable number boxes can be filled with almost any item that fits within the box dimensions. The most popular fillings include individually wrapped chocolates and candy, mini balloons, confetti, small gift items, money envelopes, pressed flowers, dried botanicals, bath bombs, small candles, cosmetics, and personalized keepsake items. For florist and event applications, boxes are often filled with fresh or dried flowers arranged in a florist foam block placed inside the box. Balloon artists use them as stuffed balloon reveal boxes. The creative possibilities are nearly unlimited.
Can I order fillable number boxes in two-digit combinations?
Yes. Two-digit number combinations for milestone ages (18, 21, 30, 40, 50, 60, 70, 80, 90) and years are available. These can be produced as two separate numeral boxes that are displayed side by side, or as a connected two-digit format if you prefer a unified presentation. Please specify your preferred configuration when requesting your quote. Minimum order quantities apply per numeral digit, so planning your full range inventory at the time of ordering is the most cost-effective approach.
What is the minimum order quantity for custom number boxes?
The minimum order is 50 units per numeral or design variant. For gifting businesses and florists launching a number box product line, ordering multiple numerals at the same time allows you to build inventory across the full digit range while qualifying for a single production run. Contact our team for guidance on a launch inventory plan that balances coverage with initial investment.
How are the number boxes assembled and filled?
Number boxes are delivered flat-packed for efficient shipping and storage. Assembly is straightforward: the box folds along pre-scored lines and locks into its numeral shape without glue or tools in most constructions. The separate lid section is set aside while the box is filled, then placed on top to complete the presentation. Assembly instructions are included with every order. Most businesses find that boxes can be assembled and filled in three to five minutes per unit once the process is familiar.
Can I have my brand name or logo printed on the fillable number boxes?
Yes. Full custom branding including your logo, brand name, website, and social media handles can be incorporated into the exterior design of your branded fillable number boxes. Many gifting businesses print subtle branding on the base or rear panel of each numeral, creating a professional branded presentation without distracting from the primary decorative design on the face of the box. Branded number boxes are excellent for social media visibility as customers often photograph and share them, extending your brand reach organically. Our custom display boxes and custom subscription boxes are also worth exploring if you are building a broader branded gifting product line.
