Overview
Chumia's set packs 8 precision screwdrivers aimed at watch repair and other micro fastener work, with a total listed weight of 0.23 pounds. The listing's piece count field shows 1, which reads as the sale unit rather than a contradiction of the 8-piece title.
Precision driver sets like this exist to reach screws that standard-size drivers can't turn, the kind found in watch backs, eyeglass hinges and small electronics.
