This is a cat-tattoo (cattoo) stamp which you can use to put a funny looking cat on your skin. The cattoo is reusable many times and if you use a waterproof ink, the tattoo lasts for several days (if you do not shower much ;)). Originally, the tattoo was designed by William Osman (https://www.youtube.com/channel/UCfMJ2MchTSW2kWaT0kK94Yw). Check out his channel and leave a thumbs up!
