CRAFTS4U Adhesive Magnetic Sheets are designed to be used with the CRAFTS4U Stamp Storage Cases so you can store your stamps with the coordinating dies all together and put the design into the outside pocket for easy identification. For that reason these magnetic sheets can be trimmed using ordinary scissors to your desired size and then the protective sheet on adhesive side is removed and the adhesive magnetic sheet is stuck inside the Stamp Storage Case. Each Adhesive Magnetic Sheet is 126 x 210mm.
