It is a 3-part system composed of a clip, a wedge and a plier. The design is very easy to learn and apply, no matter what your experience level is. As we already mentioned, Gunsen always seeks for innovation. That’s why we produce clips from 0,5mm up to 5mm which can be used for tiles/stones between 3mm -30mm sizes. Yes, that’s the widest range in market 😊
