DBI/SALA Tan and Black Small Parts Canvas Pouch With Innovative Self-Closure System. Designed with drop prevention in mind, our patented Small Parts Pouch guards against accidental drops the moment something is put inside. With an innovative self-closure system that traps objects inside, the Small Parts Pouch makes it nearly impossible for objects to fall out once placed in the bag, while making it easy for retrieval by the user since no opening or closing is necessary.
