This item was found during a decluttering of my parents' home. The purchase date is unknown, but it's quite old. Although it's new, it has been stored at home and shows some signs of aging. There are no issues with its usability. Please check the photos for the condition before purchasing. Features: ● The fit ring embedded in the tapered head securely grips the cap bolt, allowing for one-handed insertion into the desired screw hole, improving work efficiency. (2.5, 3, 4, 5, 6, 8, 10mm) ● The hex key material uses special alloy steel SNCM+V Special, and the finish is hard chrome plating for excellent durability. ● Set in a compact 2-tier holder.
