Corona Lime Slicer
from margarita fun to apple's n' peanut butter. this saves so much time and work.
Glass water bottles. Awesome.
I like breaking this one out when I have my snobby wine friends over for dinner. Then they feel slightly stupid when they're swirling and sniffing their wine out of a dixie cup glass.
looks great and it will prevent alcohol abuse (aka spilling the perfect martini all over your kitchen).
