超細微玻璃纖維補充包（12入）

Nice to have a dozen of these in one pack, since the bristles fray after heavy use on old paint. Perfect for getting into tight crevices on small parts.

The individual filaments are stiff enough to scrub dried paint off my metal parts without scratching. Twelve refills in a pack means I won’t have to reorder for months. This is exactly what I needed for detailed cleaning.

First time using fiberglass for cleaning small parts and it really does get into tight grooves without scratching. The pack of 12 means I can swap refills often without worrying about running out.
