Went to Kamena to frame an art print with a frame purchased at a different retailer. The staff member at Kamena was very helpful and patient when we were picking the matte, but the first one they offered was a custom matte - much more expensive than we were quoted on the phone. After we clarified this, we opted to use a matte that they had already in stock, which was significantly cheaper. They framed the art right away as we waited and it turned out ok - slightly off-center (by 2 mm) and not absolutely square, but for $20, can't expect much more. We are satisfied with the cost of the matte and timeliness of the service, but will not return for any future projects.
