Don't worry if you don't live in the NYC area- Brooklyn 5&10.com is based in Brooklyn, but it's an online store. You'll find a fun selection of whimsical gifts and crafts on their site. Right now they're having a "Supa-Spring Sale."
The Domus Coin Bank is designed by the Danes and modeled after European architecture. So, not only does it look cute, but once they snap it together, it can help your little ones learn how to save.
We love these tin replicas of a Czech car called the Tatra made by a Czech company called Tin Toys Kovap. Use a key to wind it up and watch it go. The best part- the bumper keeps it from falling off tables.
Choki-ori is the new paper craft from Japan. It's a great introductory activity for ages 5 and up who aren't quite ready for origami yet. Just cut along the lines and fold to create these farm friends.
More fun than a regular puzzle, Nueve is a set of handcrafted wooden cubes that can form billions of patterns. Designed by newartifacts in Uruguay, they're made of hardwood and silk-screened in red.
There are loads more unusual things to see at Brooklyn 5&10.com, many of which would be the hit of a birthday party.
