used MK professional blades with tons of sharpening left! They are 9 and 1/2 in blades. They have been sharpened maybe 7 times. 75.00 plus shipping. I will send pics on request. They were well cared for. They are currently on a pair of womens 5 A Riedell Gold Star boots. I am willing to sell as a set, but the boot has been well used. It is still usable, but not for a higher level skater. I would use only for a skater learning single jumps, not including axels. I would sell the set for 85.00 plus shipping. PM me if interested.
