No more dust and other deposits in open sockets. Thanks to the practical and robust socket brushes from SAUBA. Also suitable for Type J sockets: simply insert the brush into the socket, rock it back and forth vigorously, and you're done. Completely safe. No tedious handling with rags or cotton swabs, no unscrewing the socket, and no risk of electric shock. The brush at the end of the handle is ideal for cleaning keyboards, light switches, crevices, and other nooks and crannies. Like all SAUBA products, it's made from recycled plastic and manufactured in Germany.
