It makes sense to have another tattoo tong for your herd identification letters. The .300 tattoo outfit is ideal for tattooing LaMancha tail webs and the small ears of Swiss breed kids. Tattoo tongs are 7" long; head is only 1 1/4" wide (about half as wide as the 5/16 inch tattoo tong's head). Head holds four digits. The .300 digits are as tall as the 5/16 tattoo digits, but they are spaced closer in head, making a more compact tattoo mark. The .300 tattoo digits are not designed for use with 5/16 tattoo tongs. Good quality Stone construction: Strong lightweight aluminum tongs, locking tabs on digits. Not available with ear release. For convenience, you may want to order an extra set of tongs to hold your breeder's letters. Alphabet letters are not included with the outfit and must be ordered separately.
