Description

Kids’ bedroom doors get proper security with this penguin sign: a penguin under a bold WARNING header declares the property protected by a highly trained penguin. It’s printed directly on lightweight, rust proof aluminum with slightly rounded corners, and the bright clean finish suits a playroom while the wood look fits a cabin bunk room.

Is it a good fit for a kid’s room? Yes. A 6x6 or 8x8 square sits nicely on a bedroom door at a small kid’s eye level. The disclaimer is clearly a joke, but email us if you’d like gentler custom wording.
