If someone showed this to me and asked me to guess a price, I'd say "maximum 30 USD, most likely around 20 tho." It looks nicely made, but let's be honest here, it's something that would be found in the children's jewelry section.

150 is definitely a hard pass. Even 100 would have me laugh in your face. I've never heard of Q-Pot, but maybe it's famous enough in Japan that it could sell for 150. Unfortunately, unless there's a huge discount going on, I would never even consider this... BUT for the price I got it at (albeit it being in TOM points), I actually like it. It's rather cute.
