Fastener folders are made of extremely durable, 25 point pressboard covers to withstand heavy use. 2" embedded fasteners in positions No. 1 and 3 on the covers keep legal-size documents secure and allow subdividing within folders. Also use the fasteners to keep documents in sequential order. Matching Tyvek tape spine expands up to 1" with your projects. Standard-size top tabs with an undercut score on the front cover provide room for labels or handwritten titles. Tabs are 1/3 cut in assorted positions for easy organizing and file identification. Fastener folders also offer a high percentage of recycled material.
