Crafters and office workers, this 10-pack of replacement blades will keep your paper trimmer cutting like new! These blades are designed to work with BAOFALI, Firbon, LETION, and WORKLION paper cutters (though not compatible with Fiskars and some other brands). The safety guard design is seriously smart - the blade stays hidden and only engages when you press down, which prevents accidental cuts and makes them much safer to handle, especially if you have kids around. Each blade measures about 1x1 inch and can cleanly cut through up to 12 sheets of standard 70g/m² paper, though using 5 sheets or less will significantly extend the blade's lifespan. The titanium coating makes them three times harder than regular steel, so they stay sharp through plenty of use. Replacement is straightforward - just slide your cutter's blade carriage to the center, gently separate the clear bars, and swap out the old blade for a new one. Whether you're working on scrapbooking, photo trimming, coupon cutting, or any paper craft project, having sharp blades makes all the difference in getting clean, professional-looking cuts. With 10 blades in the pack, you'll be set for a long time. It's one of those simple supplies that completely transforms your paper cutting experience from frustrating to fantastic!
