You only ever need one measuring spoon at a time.  You don't need the rest of them getting in the way, and you certainly don't need to wash the whole set every time you use one.  For these reasons, the Tupperware measuring spoons snap on and off the ring.  Genius!

Consists of 1ml, 2ml, 5ml (teaspoon), 15ml (Tablespoon) and 25ml spoons.
