Abstract
The invention provides a container having a roll of abrasive adhesive discs releasably connected to a backing paper inside the container. The container is designed such that the discs and backing paper may be pulled from the upper front of the container and when the backing paper is pulled downward or outward over the front edge the abrasive discs release from the backing paper and are popped free and released from the backing paper while being presented for easy removal by the user without contamination of the adhesive surface. Alternatively, by pulling the backing generally upward from the device, the abrasive discs remain adhered to the backing paper and the backing paper can be cut or manually torn such that one or several of the discs may be pulled free from the device while remaining on the backing and removed to another work place for later use without risk of contamination of the adhesive backing.
