We have many of these tips. We'd like to have fewer. Maybe you can help us out. These tips have been in the storage closet for so long, no one knows where they came from. The tips are in excellent condition. This Hexacon tip is extra long (3-3/4") with a 3/8" shank and a 1/8" chisel point. Fits our larger Esico Soldering Irons (100W and 200W) iron. These quality tips are a great value at this price.
