Cute teacup with an element of surprise. I remember several years ago, a friend of mine gifted her husband a mug with a similar concept, she filled it up with dark coffee, so he wouldn’t get suspicious. And was pleasantly surprised as he drank and saw what was in it and burst out laughing because of its naughty design. Reaction: priceless.
Same good fun with Hidden Animal Teacup that’s perfect as a present. It comes in different fun designs too.
