This is just speculation but it's probably low quality stuff made in China. There are a ton of random sellers on Amazon now. Best way to rate a product is to read the reviews. My guess is it will work but it will feel and look cheap. You may notice imperfections and design defects. If you break a lot of bowls, go for it. If you want something decent that will last you a long time, get it in a head shop.
Exactly. That design makes no sense. Read the reviews, if you put water in it, it just ends up in your mouth. Then look at the design... yup, sure would end up in your mouth lol!
