What a fun way to show off your love for the game of tennis than with a tennis ball can keyring! Whether you're a tennis coach, a gun player with a ripping forehand or simply an avid tennis fan, this cute keyring is the perfect accessory for you! (Matching earrings also available - Tennis Balls earrings) [Tennis balls can approx. 30mm(h)] Please note: these keyrings are NOT waterproof! While they are varnished for durability and handling, they are made from wood and paper, so Cheeky Little Monkeys does not recommend getting them wet.
