Hi, Steve,
That particular brand was Gravoply (made by Gravograph) but I have since moved away from them to Rowmark and IPI as Gravograph has been doing some pretty crappy things to their (good) customers like changing material types without notifying the customers in any way. In other words, they used to send me certain materials and when I needed to order more, they would then send new materials (by ordering the same part number) that didn't look, or even cut like the original material. On top of that, if you didn't want the new material, you could send it back on YOUR cost. Not the kind of company I will deal with so I've moved on.
Hope that helps-
Dave
