Size: Medium (Pack of 1) Color: White
I gave this as a gag gift for a friend's 75th birthday. Everyone thought it was very funny. I don't know what you'd want wet underwear for but as a gag gift it's a hit.

  • Much smaller than pictured
Size: Medium (Pack of 1) Color: White
Bought as a gag gift, never used it but I was surprised how small the can is. I think its over priced. Bit got a lot of laughs and was a good gift. I wonder if it actually works.
