Description Plug Cup
Are your colleagues driving you crazy because they constantly use your cup in the office? Then this cup can now provide a solution:
The plug cup has a strategically placed hole in the lower half, which can only be closed with the matching plug. You can easily carry this plug on your keychain, so no one but you can use the cup, as any content will simply run out. You will never have trouble finding a cup in the office kitchen again.
The cup is made entirely of ceramic, and the plug is made of soft plastic with a key ring.
