These are casters for 2-sided & 3-sided bounce boards made by Oya Shoji. You can easily and inexpensively create mobile bounce boards (reflectors, kapok boards) by buying boards at a home center, etc. The condition is almost unused, but there are scratches due to friction between the metals during storage. However, the caster parts and welds have no rust and are perfectly functional. One of the seven casters is missing the screw to fix the board, but it can be purchased at a home center for a few hundred yen. The new price is about 7700 yen per piece, so I have set the price at about 5500 yen per piece, but some discount is possible. - Type: Caster - Material: Metal - Quantity: 7 - Application: For bounce boards - Features: For two-sided boards Thank you for viewing. Please purchase with the 3N rule (no returns, no refunds, no exchanges).
