Tiiyee Fiberglass Scratch Brush Pen, Fiberglass Nylon Pen Prep Sanding Brushes Watch Rust Remove Clean Tool for Corrosion Jewelry Repair Coin Cleaning Electronic Applications Circuit Boards Auto Work

Simple but useful little tool to clean up any Electrical parts such as brush contacts.

Wears out too fast

Fountain pen style tool which should prove useful when cleaning model railway.

The first thing I want to say is that this is not a set, it is just one scratch pen, which is very cheaply made and yet the price is sky-high for what you are getting. This scratch pen is just over 4 inches long and by turning the black head the stiff fibreglass wires retract in an, you do a reasonably long fibreglass part, but the price is simply not justifiable. On a positive note, it does work and cleans tarnished metal parts, but I cannot recommend it at this price, if you had perhaps three, then it would be worth the money, but at this price and the cheapness of the material, I can only give it three stars.

Der Stift ist prima an Stellen wo man schlecht dran kommt.

Ottima qualità/prezzo

It works but a bit flimsy

Fibra molto poco efficace, troppo morbida. Nel caso di un circuito stampato "accerezza" lo strato protettivo ed è poco utile

Effektiv um Rost zu entfernen, oder um schnell und einfach kleine Kratzer aus Edelstahl und Titan zu polieren!
