TBC Bushings and Holders
TBC bushings are custom made for our engraved cartridge pen kits since they are not standard size in any bushing sets currently available. Top end fits the Euro / Designer Pen Clip and the Bottom end fits the 30 Caliber (Bullet) Cartridge Lower Half Assembly provided in the kit.
We purchased a large quantity of white and black pop-top bushing containers for our own use, and are passing on the bulk purchase extras to our customers. The top snaps tightly and the cylinder is tall enough to fit every size pen bushing set we have in the white, and most single barrel bushings in the smaller black containers.
