OLFA 45mm Rotary Cutter Replacement Blades, 5 Blades (RB45-5) - Tungsten Steel Circular Rotary Fabric Cutter Blade for Quilting, Sewing, Crafts, and Scrapbooking Fits Most 45mm Rotary Cutters

Totally satisfied. These sell for $9.99 as singleblades so this is a great deal! Genuine Olfa!

I think the postage and handling charges are an add on to the blade price and there would have to be a number of blades to make ordering them feasible.

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

Ive tried other brands blades but always come back to Olfa! They stay the sharpest longest, they cut through many layers of fabric at a time. (Ive cut 6!) which significantly cuts down on time when you are cutting itty bitty pieces for a quilt! Ive also cut paper with these blades so nice! Just make sure you close the safety on it as they are super sharp. Ill admit to a trip to the emergency room and some stitches when I neglected the safety on this... Also for the amazon.com price you cant beat even with a great sale at your local fabric/quilt/craft store!!!

Olfa blades are a quality item. Ive bought off brands and not been happy as they have chips or arent as sharp as the Olfas

Could not cut with the blades that came with my cutter. These blades made all the difference....cut like BUTTER.

from semi transparent packaging - the hole looks just to be round but when you open you see it is the right shape as shown think I could have used round hole ones - but this shape was on my board from someone using on an old dark gray Fiskar board with an orange guard and orange grid - seems to work fine

At the price I can blades for frequently

These are the best blades. The generics are not worth it. This metal is different than others. I can cut through multiple layers of fabric with ease. These blades last a long time and do not slowly chip like cheaper blades. Others that Ive tried will either not cut, or will only cut 1-2 layers, or worse they will get chipped and leave a dotted line of uncut fabric. These blades are strong and long lasting. I love them!
