These are the best ever! A teacher in my school uses these when her class does crafts or they use the FORBIDDEN GLITTER. It works like a masking tape lint roller only it is HUGE! The kids use it to roll the small pieces of trash and glitter right up! It works much better than a broom because it doesn't leave anything behind. She also uses it to clean her carpet when the school's vacuum isn't working. It is AWESOME!
