New, unused DECATHLON Strength Training Elastic Band Set 10lbs, 15lbs, 20lbs Set of 3 Width: 4cm [High elasticity, durable, and resistant to tearing]: Possesses strong elasticity while achieving high durability that can withstand repeated use. The cut edges are neatly finished, the thickness is uniform, and there is no worry of tearing even when pulled with force. This is a quality that professional trainers can use with confidence. I purchased these for approximately 1,000 yen each. As I am already listing them at a low price, please refrain from negotiating further. No price reductions
