All our cases are made with a sturdy plastic called polypropylene. Our cases have their own bright colors and come with a living hinge and snap closure. The living hinge allows the case to be open and closed many, many times. The snap closure insures the product stays securely shut while not in use. All cases are patented. They were designed to look exactly like the items they hold. This makes it easier to locate them even in the dark. The Large scissors case is designed to hold the average 8" scissors. The Dual scissors case is designed to hold two pair of 5 1/2" or smaller designer scissors. The Dual scissors case has a strap on each side that allows you to secure both pair. This also keeps them from moving around in the case and prevents scratching or damaging. The Deluxe Rotary case was designed to hold the 45 mm rotary cutter. A rotary cutter is a very razor sharp cutter that most quilters use. The cutter allows the quilter to cut several layers of fabric precisely and quickly. We have several more patents pending on new items that will help us continue to "Shield and Protect With Class."
