This is a set of three GD IRON GRIPs, one each of 70, 80, and 90! GD IRON GRIP 70 20kg 30kg 40kg 50kg 60kg 70kg GD IRON GRIP 80 25kg 36kg 47kg 58kg 69kg 80kg GD IRON GRIP 90 25kg 38kg 51kg 64kg 77kg 90kg By owning all three, you can handle the following weights: 20kg, 25kg, 25kg, 30kg, 36kg, 38kg, 40kg, 47kg, 50kg, 51kg, 58kg, 60kg, 64kg, 69kg, 70kg, 77kg, 80kg, and 90kg. I used YONEX grip tape, so there are no scratches or stains on the grip part of the main body. Also, the tape has not adhered to the grip, so please rest assured. I have not dropped them or given them any strong impacts, so there are no noticeable scratches. Instant purchase is OK!
