Mermaid Decor
Make a splash at your kid's birthday party with mermaid-themed decor, supplies, and thingamabobs, from shell-inspired tableware to balloons that shimmer like the sea.

Reel in unique mermaid birthday decorations from Paperless Post Party Shop so you don’t feel like a fish out of water when planning. We offer a wide variety of items available right at your fin-tips so you can easily create an underwater world. With all that convenience, you can focus on having a shell of a good time instead.

Greet guests with mermaid-themed balloons, banners, and hanging decorations from the ceiling to transform your party room into a modern-day Atlantis. 

Keep surfaces protected from spills with tablecloths and runners, and top them off with must-haves like plates, napkins, and flatware. Find cups with mermaid scale designs and fill them with blue-tinted juice to mimic the ocean. Don’t forget straws and stir sticks to mix in fresh fruit slices.

Let the kids tackle a piñata—but remind them to save room for dessert. No matter what delicious goodies are on the menu, put them on a pedestal with a fancy cake stand. We also have cupcake kits with sea-inspired wrappers and an assortment of charming cake toppers.
