DIY star. A hallmarked solid sterling silver screwdriver pendant. This crosshead screwdriver has a ridged handle detailing and comes on an 30"/75cm long sterling silver box chain (long enough to go over the head) with a polished finish. Unisex. A screwdriver pin is also available. The screwdriver actually works to tighten crosshead screws on glasses and sunglasses (note: silver is softer than steel, so be gentle and don't over tighten or you will damage the tip!).
