SWAROVSKI Application Test Pen

The SWAROVSKI Test Pen has been designed to work in conjunction with the SWAROVSKI CG500-35 glue. The pen will test for surface tension of at least 38mN/m or more as is recommended by SWAROVSKI ELEMENTS. How to Use: 1. Before gluing, mark the representative surface sample. 2. If the ink remains visiable for 2 seconds, the surface is suitable for gluing. 3. If the ink disappears or forms bubbles, the surface is not suitable for gluing. In this case, a pre-treatment cleaning method should be checked.
