This is Bell's Camping's BB01 glow-in-the-dark item. I purchased these for coasters, and I used one of the two. I'm selling the other one as I don't need it. Would these be suitable for coasters, etc.? I opened the bottom half of the package and took out one of them, but I haven't taken out the other one. I will seal it with tape and ship it as is. I'm not considering lowering the price, so please consider the current price.
