If you're considering buying new, you might want to consider this as well. While not exactly "like new," it has hardly been used. I bought it with high hopes, but my arm strength just couldn't keep up with 8kg. I got a herniated disc. I tried to get stronger, but I got weaker. Learn from my example, and choose dumbbells that are right for you. So, I'm selling these. Two 8kg dumbbells, for a total of 16kg. Retail price: 7300 yen The surface is coated with PVC resin, making it non-slip and easy to handle. (If you can lift them, that is.) I believe they are probably discontinued now.
