Love these blades so far! They’re so sharp and fit on my cutter. Originally I had reviewed this product and gave it only 3 stars as my product only came with 9 blades instead of 10. I tried counting them 3x and had my bf count them as well to make sure none were sticking together since they have an oily coating when you first open the packaging and there were for sure only 9 blades. BUT the following day after I posted my review, the seller emailed me apologizing for the mistake and asking if I’d like them to ship me a new pack for free! That’s some great customer service. For the price and quality, i am extremely satisfied with this solution!
