"That One Sibling" Mug

That one sibling. Definition: you know who this is.

Every family has one. Some families have two. Same words as our That One Sibling shirt.

The details: White ceramic mug in 11 oz or 15 oz. The design is printed on both sides, so it reads right in either hand. Microwave and dishwasher safe. Printed to order, which is why it isn't sitting in a warehouse somewhere.
