This is a handmade cover for Mrs. GREEN APPLE penlights. It can be attached and detached with Velcro. Of course, it's great for live performances!! It's also cute for photoshoots, displaying at home, or in your Mrs. GREEN APPLE corner ^_^ You can also use it at live viewings in movie theaters. Some people don't use penlights, so using a cover can slightly reduce the brightness of the penlight. Penlight not included. Cover only. Thank you for looking.
