Review on Plastic Liquor Drinks Concealable Drinking by Sam Rao

Through trial and error, I found that this product didn't live up to my expectations. It may be advertised as concealable, but any industrial and scientific application would likely render it ineffective in a professional setting. The pros are essentially non-existent, and the only con is the lack of quality materials. Overall, it was a questionable purchase that I wouldn't make again.
