Great question—size affects what you can serve. On this page, many fillable number boxes are around 10 inches long, with some larger options listed. Depth and internal width vary by style.

• Mini cupcakes usually fit better than standard cupcakes in most cardboard number trays.
• Strawberries, candies, nuts, and small cookies tend to fit comfortably.
• Check the dimensions in the product description, especially the interior cavity width and height.
• Test capacity by placing a few unwrapped items in a clean, empty box before final setup.

If you need to serve larger treats or want extra room, consider the bigger sizes noted on the product pages. Fit can vary by design, so a quick measure can help you choose confidently.

Most cardboard number trays arrive flat and are designed for quick setup. Here’s a simple approach that can help:

1. Fold and lock tabs along the edges so the walls stand upright and snug.
2. Add a barrier such as parchment, doilies, or cupcake liners to help keep the tray clean.
3. Place heavier items first to create a stable base, then layer lighter treats.
4. Aim for even weight by distributing items across the number so it’s easier to move.
5. Chill perishable items before arranging to minimize handling time at room temp.

Some options are plastic and arrive pre-formed; a gentle rinse and dry before use can be helpful. Setups can differ by product design, so refer to included instructions when available.

Reuse often depends on the box’s condition after your event. Cardboard number trays can sometimes be reused if they stay clean and dry.

• Use liners (parchment, doilies, or cupcake liners) during the event to reduce residue.
• Afterward, empty the tray and gently wipe away crumbs with a dry cloth.
• Avoid soaking or heavy moisture, which may weaken cardboard.
• Store flat in a cool, dry place to help preserve shape for next time.
• Plastic styles can typically be hand washed and dried for future use.

Longevity varies by material and how the tray was used. If a box becomes stained or softened, repurposing it for non-food decor could be a practical option.

It varies by item. Some fillable number boxes include clear lids, while others are open-top trays.

• Check “what’s included” and photos on the product page for lid details.
• No lid? Consider gently wrapping with clear cellophane or plastic wrap.
• Use a base (like a sheet pan) and add a non-slip liner to reduce shifting.
• Carry level and avoid stacking to help protect your arrangement.
• Transport tip: If possible, fill on-site to minimize movement.

Size and design vary, so a quick measure can help you match a cover or box top that sits comfortably over the tray without pressing on your treats.

Start with the digits you need—many listings offer pre-bundled year sets (like 2025 or 2026) and single numbers for custom ages or anniversaries.

• Match your theme: Choose colors (e.g., white, black, silver) that pair with your school or party palette.
• Check dimensions: Height and width affect table fit and centerpiece impact.
• Plan the fill: Candy, mini desserts, or small favors can create a cohesive look.
• Layer decor: Pair with balloons, banners, and tableware for a polished setup.
• Convenience: Use Walmart’s filters, delivery, or pickup options for easy planning.

Availability can vary by season and store, so ordering ahead can help secure the digits and styles you want.
