NSP™ clays contain a higher percentage of wax components making them somewhat “tougher”. Available in Soft, Medium or Hard, these clays have good adhesive qualities, flexibility and length. Because they are “tougher” NSP™ tend to accept cut detail lines very cleanly, with no ragged edges. The surface texture of NSP™ will be somewhat “grabby” when compared to sulfur-based clays and even the NSP™ – Soft is rather firm by some standards.
Available in Green, Brown, and Tan
