Thanks to the excellent wetting properties of the active ingredients, solder flows and adheres beautifully along the copper tape! ♪(^^) This is a powerful 100cc capacity type. It is used not only in our atelier, but also in classrooms nationwide(^^) Please note that we offer contactless delivery and will ship in a thin container for postal drop-off.
