Touted as the thinnest full-sized professional keyboard ever made at 25.7mm thin, the Roli Seaboard GRAND features 88 keywaves echoing the 88 keys of a standard piano. There’s a bespoke, integrated stand made of anodised milled aluminum providing with a robust support even the most vehement musicians. Despite the metal stand, the weight of the whole instrument is just 12 kg. Only 88 units of the Seaboard GRAND are made, each individually engraved and priced at $8,888.88.
