The DIY Pen is a unique kit from Fraser Ross art & design studio who is based in Glasgow Scotland. The kit combines plywood, rubber heat shrink tubing and ballpoint pen components. The plywood sheet holds the individual parts that create the skeleton of the pen. It also doubles as a fixture for the last step which requires a hair dryer. The kits are available in 6 colors and are priced at £14.99 which converts to about $24.22 US. It never occurred to me to use heat shrink tubing to make my own pen, but now that I’ve seen this, it sparks a few ideas. Anyone out there make their own writing instruments?
