Piano Insulators for Upright Pianos

Thank you for looking.

This is a set of 4 rubber insulators designed to absorb piano sound. The bottom surface is made of felt.
These were purchased for an upright piano for soundproofing and earthquake resistance, but are now being sold because the piano has been disposed of and they are no longer needed.
They were placed under the upright piano.
They were purchased for ¥5,000 each, for a total value of ¥20,000.

There are no functional issues, but please check the photos.
We kindly ask for your consideration, understanding that these are used items.

◎We aim to ship within 1 to 2 days after your order.

[Product Description]
Piano Caster Cups, Set of 4, for Upright Pianos, Foot Pads, Non-slip, Vibration Damping, Stress Dispersion, Moisture Prevention, Piano Wheel Cups

[Stress Dispersion] Piano caster cups can protect piano wheels and floors from scratches by dispersing the stress on the piano wheels.
[Non-slip Processing] The EVA mat on the bottom has a non-slip finish, so even if the casters rotate, the piano will remain in its fixed position and will not move.
[Do Not Disturb Family or Neighbors] The EVA pads can isolate most sound from being transmitted to the floor, so practicing will not disturb your family or neighbors through the floor.
[Vibration Damping] The vibration-damping EVA pads can reduce damage to internal piano parts caused by vibrations, extending the lifespan of the parts.
[Moisture Prevention] To some extent, they can prevent moisture by blocking direct contact between the piano and the floor.
