thin fasteners - premated use for photo albums

Wafer Thin Oval fasteners take the work out of projects and provide total convenience. They are pre-mated and pre-sized with an adhesive back for simple peel and stick application. An easy peel tab makes it a snap to quickly remove the release liner and fasten items. The wafer thin profile provides a strong fastening closure with ease of use and adjustability surpassing double stick tape or glue. Key uses include: binder closures, book covers, scrapbooks, photo albums, card-making, paper arts, attaching cards and notes to display boards, calendars, and planners.
