If you are planning to propose to your girlfriend but need to keep the ring hidden until you pop the question, get yourself some I-Do-Derant.

It looks like a travel-sized deodorant, but it has a secret compartment to hold an engagement ring. That way your rock stays out of site, and out of your pocket.

The deodorant is cleverly titled "The Rock" and has a diamond symbol on it - so you won't get it confused with your regular travel deodorant. There has been a 44% increase in purchases of the deodorant as Valentine's Day approaches.
