In a moment of calm before people arrived and dinner got started, I tried to get a decent picture of the bottle. If you look closely, it has a little keitai strap charm hanging around the neck. It reads 噴き出し注意 or “Caution! Spouting!”. When I bought this, the staff at the store were careful to warn me and I did need a towel to catch some of the overflow. The little warning charm will probably go on my keychain or phone soon.
