The shape is a rectangle, with a curved surface on the top and bottom.  It's as if you took two 1/4 sections of pipe and set them on top of each other.  You have a flat end near the mandrel, a curved surface that meets at a point on the edges adjacent the mandrel. This is great for a small focal but it will also make fabulous chunky bracelets and necklaces!

The press works best with 1/16th or 5/64th mandrel.  If you work primarily with 3/32nd mandrels you can select that modification, which we will provide at no charge.
