Makins Professional Ultimate Clay Machine® has a super wide 180mm non stick roller and 9 thickness settings. Although the Ultimate Clay Machine® can be used with all brands of Polymer Clay, it works best with Makin’s Clay® because it was manufactured specifically for use with Makin’s Clay® which is very soft straight out of the packet. Results may vary if the Ultimate Clay Machine® is used with brands of clay other than Makin’s Clay®. We have no control over the manufacturing process of clays other than the Makin’s ® brand and cannot guarantee the results, quality or consistency of the Professional Ultimate Clay Machine®, when used with other brands of clay. It is important to roll other brands of clay through the Ultimate Clay Machine® using progressive settings to avoid damage by forcing the rollers apart. We strongly recommend using soft clay.
