I purchased this for home practice around June 2025 for 25,490 yen. I've used it a few times, but I no longer need it, so I'm selling it. The price includes shipping. Here are the selling points of the sandbag as advertised: 【Selling Points】 1. Suitable for practicing contact sports. For sports like rugby, when using it as a tackle mitt, you'll often approach the target diagonally rather than straight on. While a cylindrical sandbag allows tackling from any direction, a square sandbag has corners, making it easier to visually grasp the positioning of tackling diagonally, focusing on the corners. 2. For those using it for fitness purposes, such as women, when practicing punches and kicks with a parallel stance, you don't fully utilize the rotational movement of your hips. Using a square sandbag allows you to practice twisting your waist, focusing on the diagonals, which helps to train the abdominal obliques and iliopsoas muscles, contributing to a more defined waistline. ■POINT 1: The areas where the chains are attached, where force is applied during strikes, are reinforced. ■POINT 2: The corners are reinforced with PP bands on the inside to improve strength. ■POINT 3: Air holes are located at the top of the main body to cushion the impact of strikes. ■POINT 4: The bottom is also reinforced with PP bands for increased durability. ■POINT 5: Includes targets. There are three targets on each of the four sides, allowing for more focused striking training. ■Size: Height: 100cm (excluding chains) Width: 35cm ■Weight: Approximately 28kg ■Material: Outer: Synthetic leather, Inside: Rags (cloth)
