Ultem material guitar picks are the ultimate in quality! Even on dull strings, these picks are sure to create crisp, clean tones. The sound of these picks is meant to resemble that of true tortoiseshell picks, but, unlike real tortoiseshell, they are not susceptible to fractures. These are some of the strongest picks on the market, and you will be sure to love the bright sounds that they produce! They are available in eight different gauges. They are tan in color, and available with the Clayton eagle logo in white epoxy (http://www.steveclayton.com/ultem.php), or for customization (http://www.claytoncustom.com)! They are also offered in three different shapes including standard, rounded triangle, and small teardrop.
