Ragproper Modern Glass Hip Flask for Men with Cork & Silicone Lid Liners - Durable Silicone Covered Flask for Whiskey, & Other Liquor (Single Shot 100ml, Black)

Todo es de plástico de buena calidad; y lo mejor la botella de vidrio con su tapadera de corcho

Admired for what it is as much as what it contained. And it does not flavour the contents.

ガラスなので劣化が少ない。内容量が見える。

Perfect product, best costumer service.

I haven't had much luck with flasks but based on what I was seeing in online reviews about the Ragproper ones, I bought one. For $28, it feels very solid and is good quality. You don't have to worry about a metal taste with the stainless steel ones. The only "bad" thing I noticed was that there were little specks of something white in the flask all along the glass so I had to wash it a few times with a silicone straw cleaner to get rid of it. Not sure what it was, but be sure to clean it before you use it. Edit: after the flask dried from cleaning it, the inside of it was already scratched up from the brush I used to clean the specks off the glass.
