There are 18 flat surfaces on this bead...6 around the outer edge, then 6 facets on the top and 6 facets on the bottom!! This is a fun shape and can really play with the light, especially with transparent glass or a nice reduction on the surface. Depending how heavy handed you are with the firepolishing will depend how pronounced those facets are.
Trio: Mini 13mm x mm, Small 15mm x mm, and Medium 18mm x mm
Large: 1" hole to hole x mm
Another other cool thing about this tool is that it can match up with the ZooziHex trio, to make flat bottom beads with the faceted top!! Simply use the top of this press with the base of the corresponding hex press, a perfect match!
