    Name brand is better! Original packaging, looks like what I would buy in the store. Great price too! I would order these again from these folks.

    I like the blades and use them for quilting. They work well for me and seem to be better than other brands.

    I just got this order, but we use this brand all the time. Theyre sharp and the edge lasts a reasonably long time.

    Love OLFA blades! Packaged individually in containers, making it easy to dispose of old blades.

    Good product. It does come in foreign packaging not usa. Was a bit odd but they seem authentic and cut excellent. The packaging was a bit damaged and one blade was a bit out of round/dull. Other than that I would rate it a five star!

    The blades I received were all stuck together, presenting a very dangerous situation. I finally managed to separate one using hemostats and tweezers but the whole time I was scared I was going to cut myself. The blades need to be individually packaged for safety! Once I was able to separate one of the blades and attach it to my Olfa 45mm rotary cutter, the new blade was duller than the original blade being replaced. I requested a refund from the seller and it was approved; however, I have to pay shipping to return the blades and the sellers shipping is going to be deducted from my refund. Additionally the seller is stating that my problem is the size of the blade not fitting my cutter. I never said there was any problem with the blade fitting my cutter. My cutter is 45mm and the blades are 45mm. I am very disappointed and will never do business with this seller again.

    I ordered these as a replacement blade for my 35mm Olaf rotary cutter and they work beautifully. The actual Olaf blades are very expensive and I found myself just buying cheap rotary cutters because they were cheaper than replacing the Olaf blade, but Im so glad I found these. A sharp blade makes a huge difference.

    am making a quilt and needed sharp blades. they came on time and was so happy how sharp they are, needed to cut multiple layers at one time, did with ease. One of the best deals I have ever gotten

    Great blades, great price (unless you feel like making a trip to Joanns with your coupon), and they get delivered to your door. Win, win,win. Dont even bother with off-brands (carpet blades???) because they are nit worth the aggravation. Buy extra so you can always have a fresh, sharp blade for you next project. BTW, save your dull ones in a separate container and use them on that old rotary cutter you have designated just for paper.
