### ⭐⭐⭐⭐⭐ Find a way to store after use
*by L***P on September 2, 2025*

You should know that it doesn’t come rolled & organized like picture shows. It’s inside a clear plastic bag that has to be cut open. Once that’s done you will have to fight it back in the bag like a disobedient drunk snake and tape the bag closed to keep it inside But it’s exactly what it says it is, works great…!
