Philmore 12-440 Fiberglass PrepPen Refill Cartridge

Features

The Philmore 12-440 Cartridge is made to serve as a refill for the 12-437 Fiberglass PrepPen. The pen is designed to prepare circuit boards and other computer hardware for soldering tasks, but when that gets worn down, this pair of Refill Cartridges replenishes the product. Each is made from a bundle of fiberglass strands that are thinner than human hair. They work like sandpaper while reaching areas that it couldn’t. It feels like an eraser to use while it smooths out rough surfaces and clears away rust, corrosion, and foreign materials. Perfect for any soldering toolkit, whether for professionals or hobbyists.
