Amazon ¥20,000 Purchased April 1st 2, PEARL Drum Throne Backrest DTBR-1535 Soundhouse ¥13,900 Purchased April 28th These are two sets. I was looking for a pressure-distributing, height-adjustable seat that was as low as possible for playing guitar while seated. I previously purchased a Tama set, but the adjustment exceeded 500mm, which was too high, so I sold it on this site. This time, I bought the Pearl set, attracted by the low type, but the minimum height setting of 445mm was not suitable for me, so I will sell it. As mentioned above, I just bought them, so they are in near-new condition. I will ship items 1 and 2 together, wrapped in bubble wrap and secured with PP band.
