Picasso's Tungsten Worm and Flipping Weights are manufactured from the same molds Tru-Tungsten used. Picasso created the fray free/ insert free manufacturing processes for Tru-Tungsten and that same process continues with Picasso's Tungsten Weights. These weights get further process and QC in our own facility in the USA, just as we did for TT. This is to assure every weight going into a package is of the highest quality and completely fray free. Made from 97% pure tungsten for the greatest sensitivity and allows the angler to detect subtle bites that would otherwise have been missed. The chip resistant Duraseal coating is ultra smooth, hard and long lasting. Fish can not hold on to tungsten weights the way they can hold onto lead which translates into a very good hook set. 50% smaller profile than lead allows for fewer hang ups and allows tungsten weights to penetrate thick cover, slop or grass using less weight. These weights are made from the same molds previously used by Tru-Tungsten, with added QA for guaranteed Fray-Free use.
