Attention crafters and sewers! This 36-pack of Coufce rotary cutter blades is about to become your new best friend in the workshop. These 45mm (that's about 1.77 inches) blades are razor-sharp and ready to slice through fabric like butter. Made from durable alloy steel, they resist rust and won't deform or break on you mid-project. They work with most popular rotary cutter brands including Fiskars, Olfa, and Martelli - perfect for replacing those dull blades that are slowing you down. You can cut through up to six layers of material at once - we're talking fabric, wool, felt, vinyl, leather, cardboard, even wallpaper. Just a heads up - they're not meant for super dense materials, but for most crafting needs, they're absolutely perfect. The silver finish looks professional, and having 36 blades means you're set for months of crafting without worrying about running out. Seriously, if you do any quilting, sewing, or scrapbooking, these replacement blades will make your projects so much smoother. Just remember to handle with care and keep them away from kids - these things are seriously sharp!
