I bought these last year on a whim and they were amazing for festivals. They are sun tan lotion containers that are designed to discretely hold liquor. I did get some funny looks while taking whiskey pulls from a sunscreen bottle though.

I am planning to get this. It should work just fine.

I used these "Sunscreen Flasks". It's just an empty flask designed to look like a sunscreen bottle so no need to worry about trying to get the sunscreen taste out because sunscreen has never been inside them before.
