Resin saver molds have been around for a number of years and was the first of these type of molds. The originator of these was Charlie at Creative Dimensions . Over the years he had Neil Pabia know on the IAP as Wolftat make these and distribute them. Neal has gone on to other things and Charlie has taken back the Resin Saver molds. He has made new masters and has also redesigned the inserts. These will be dropped shipped by Creative Dimensions and shipping will be my standard $6.95 for shipping in the US and $19.99 overseas.
