I have kept this item unused. It is a AAA half-well type cork grip (177mm long, 8.5mm inner diameter, 21.5mm diameter for embedding the reel seat, 10mm deep), and an uplock screw-type reel seat (River Peak Tiger Maple, 100mm long, 19.5g weight, 17.5mm outer diameter, approximately 10mm inner diameter, 21.5mm diameter at the top of the part embedded in the grip). I believe it is suitable for a rod of around a 5-weight.
