This device has two functions. I'll let you in on the fact that one of those functions is storage. Do you know what it is? To find out,

It's the Lekue Lemon Press and it easily squeezes lemon halves. You pop the lemon half in, and can store it until you use it again. The plugged spout on bottom allows you to set it on the table, and it prevents seeds from coming through. A set of two costs $12.99
