Another Slimline enhancement
I really enjoy this hobby! After doing a number of slimline pens with metal inserts for a bit of interest (like my most recent post), I thought I would try putting some 1/4" thick plastic in. I went to Tap Plastic and they have a cut off box. I bought a sample of Red, a White, and a Black for...www.penturners.org
Those look like Penn State kits.
