I bought this on Rakuten for 14,680 yen. There are people in the world I want to punch or even kill, but I endured with this. I'm selling it because I moved and don't have space for it. It's filled with fine gravel and sand that you can buy at a home center. It will be even heavier if you add water. Currently, it weighs over 70 kilograms. Shipping is not possible. The storage location is Mizue, Edogawa-ku. No price reductions.
