This is a set of high-quality mahjong tiles from Taiyo Unimac Co., Ltd., housed in a deluxe attache case. The tiles are large and easy to handle, with a substantial weight and feel. The tile size is 28 x 20.5 x 16.5 mm. The backs of the tiles are yellow. There are water stains on a thin "Beginner's Guidebook" pamphlet, but the score sheets are unused. These large tiles are no longer in production and are not currently sold.
