"I bought these to make sure I was getting the correct size. They are light weight and comfortable to use. After finding my size I think I could even use these while swimming in a chlorinated pool so I won't have to worry about damaging my good one. Included is some fine sandpaper to smooth out any rough edges - thoughtful touch."
