With just a home printer, a pair of scissors and a little glue, you can make your own themed boxes that look like they came straight from a party shop, at a fraction of the cost.

They’re the ideal size for sweets, small toys or a slice of birthday cake. And because you can print as many as you need, you’ll never run short, no matter how many guests are invited.

Hosting a party doesn’t need to drain your wallet, sometimes it’s the little DIY touches that make the day unforgettable.

Why Use Printable Party Boxes?

When you’re planning a party, every little detail adds up and so do the costs.

Store-bought favor boxes might look nice, but they’re often overpriced, limited in design and not always the right size for what you need. Printable party boxes give you all the charm without the high price tag and they come with a few extra perks too:

💰 Budget-friendly
Why spend a fortune on premade boxes when you can print your own for just the cost of paper and ink? One printable file gives you unlimited boxes, so you can save money while still creating a professional-looking setup.

📦 Customizable
Whether you need 5 boxes or 50, you’re in control. Print as many as you need, whenever you need them. You can also experiment with different paper weights, finishes or even add your child’s name to personalize each box.

🌈 Unique design
Most party shops stock the same few designs, which means your party can end up looking like everyone else’s. With a printable, you get a fresh, unique design that makes your celebration stand out and guests will notice the extra effort.

🎉 Fun for kids
Children love when everything matches the theme, from the cake to the decorations to the party favors. A mermaid-themed box makes the whole celebration feel magical and ties all the details together in a way that excites little guests.

Ideas for Filling the Boxes

Filling your mermaid party boxes can be just as fun as making them! Here are some ideas to delight your little guests:

Mini chocolates or sweets 🍬 – Everyone loves a little sugar treat! Think individually wrapped chocolates, candy-coated chocolates, or gummy candies. You can even choose ocean-themed candies, like blue jelly beans or fish-shaped gummies, to match the mermaid theme.
Small toys 🎀 – Add tiny treasures that kids can play with after the party. Stickers, mermaid rings, small figurines, bubbles or even a mini slinky are all great options. These are inexpensive, fun and perfect for little hands.
A slice of cake or cupcake 🧁 – If your party boxes will be handed out during the party, including a small slice of cake or a cupcake makes the gift extra special. You could even top cupcakes with edible seashells or mermaid tails for a magical touch!
Healthy treats 🍏 – Balance out the sweets with some healthier options. Dried fruit, fruit snacks or mini packs of crackers. You can wrap them in a clear bag with a ribbon to make them look festive.
Bonus idea: Tiny craft kits 🖌️ – For a creative twist, include a tiny coloring page, a small pack of crayons or a mini craft item like a bead bracelet kit. Kids love being able to create something at home after the party!
