Soldering stone packed in a small metal box is a new type of stone, very efficient to clean and tin faster the soldering iron bits.

This stone does not release a toxic smoke, stiffens itself after use, what enables to remove the residues and remains solid despite the rain. Besides its cleaning agents, it is enriched with tin metal so that the soldering iron is covered with a protecting tin plating to stay clean a long time.

• Extends lifetime of the soldering iron bits by cleaning and tinning without effort
• No continuous back and forth frictions
• No release of toxic smoke
• Very practical packaging
• Stiffens after use
• Moisture-proof
• Lasts longer than an ordinary ammonia stone
