Using a walkie talkie with your friends when you were a kid was always great fun. Passing along messages while playing pretend, coordinating a flawless prank, or just giving Morse code a try. While these aren’t exactly an every day use sort of item, they’re still fun to have around (especially if you have kids).

The Worlds Smallest Walkie Talkies are tiny, and are perfect when you want to communicate with someone else in the house, or are playing make-believe in the backyard. These are 4 x 5 x 3cm, and have a range of about 100 feet. They have the classic push to talk button, as well as the Morse code function. It’ll cost you about $32 for a pair of them, but can return the value in fun! Be mindful that if you need to replace the batteries, you will need a tiny screwdriver like those meant for glasses to get the backing off.
