It seems like the last 2 orders of fiberglass that I've received have not been as good quality as in the past. It seems like the mesh is heavier material, doesn't stick to the nail when i'm trying to apply it and doesn't disappear as well once I've applied the glue. I'm not sure if time/age does that to the strips but I just received this order. This fiberglass did have a little more sticky to it than the last box of strips that I ordered. I haven't had any complaints from my clients. It's just something I have noticed.
