【Instant purchase welcome!】 This is an I.L.R.I.C.H mouthpiece, 6GS for large shank. It is believed to be manufactured before the current EPM brand. Rim inner diameter: 25.4mm Bore: 7.0mm Weight: Approximately 205g (actual measurement) Cup: Medium deep It is an intermediate size between I.L.R.I.C.H's 6G and 6AL, and is recommended for players who seek a more soloistic tone. The cup is relatively small, but it still provides a rich tone. It is a rare size, as it is not often listed on Mercari. There are some scratches on the rim surface, but otherwise it is in clean condition. Shipping will be via Yu-Yu Mercari Mail (Yu-Packet Plus). Since there is no original box, we will take measures to prevent water damage and carefully pack and ship it. We will use recycled materials for packaging. Thank you very much.
