  • Excellent, great backup option for filled undies.
Size: Medium (Pack of 1) Color: White
What did I like or dislike? What did I use the product for? Great questions Amazon! Well first things first, I like that I can carry this little undie backup kit anywhere. Tremendous! It was always awkward when people would ask about the spare undies in my back pocket. Now they just think I've got a can of chew. That more or less answers what I use them for. From time to time a guy gets to the toilet a bit late and needs a backup. Now what I don't like, they don't hold up well to washings. Very disappointing. Now I order these a case at a time! Think about it! ... show more

  • Funny White Elephant gift
Size: Medium (Pack of 1) Color: White
For the first time family decided an Adult White Elephant gift exchange was needed this year. We decided the amount and the gifts would not be opened until the end. Well this gift had everyone roaring when opened. However the recipient kept asking why they needed to add water, which only made it funnier. ... show more

  • 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.
