20kg x 2 sets (40kg) 【Polyethylene Dumbbells】 These dumbbells make the most of polyethylene material. They are versatile training equipment that can be used as dumbbells or barbells. 【Won't scratch floors, and are quiet】 The outer material uses durable polyethylene, and the circular design means that, unlike iron, they won't scratch the floor even when placed directly on it. Even if the dumbbells bump into each other, they won't make a "clanging" noise, so you won't disturb those around you. 【Convenient 3-WAY Specification】 (1) Single dumbbell specification (2) Barbell specification with plates attached to both ends (3) Barbell specification with plates attached in a total of 4 places Since there are two dumbbell shafts, you can train with one hand or both hands.
