A superior double sided Sticky Mat 254 x 200 mm to fit the GEM-FX, GEM-FX4, GEM-CX4 and GEM-CX5 Bed. This will hold medium to large flat sheet material when engraving, without using double sided tape. Unlike ordinary Sticky Mat this has extraordinary holding strength, very long lasting, self healing, use both sides, virtually impervious to engraving swarf, just wash in warm soapy water and it's like new. Of course continued cuts over a long period of time will degrade the effectiveness of it. Many small enclosed cuts (closed path such as a series of circles, or squares) could cause sections of the mat to come out which of course would degrade its performance.
