If you have Boer goats, Nubians or just want a larger tattoo, the 3/8 inch tattoo outfit is the one for you. The 3/8 inch tongs comes with a positive ear release which lifts the needles, preventing scratches and blurred tattoo marks. Similar in size to our 5/16 inch tongs, the 3/8 inch tongs holds four digits and is made of the same strong, lightweight aluminum alloy as the other two Stone tattoo tongs we carry. Digits have rust-resistant nickel-plated needles and can't be put in upside down. Complete 3/8 inch tattoo outfit contains tongs, set of numbers 0-9, and black ink. For convenience, buy an extra set of tongs to hold your breeder's identifying letters. Alphabet letters must be ordered separately. 3/8 inch digits will not fit in either the 5/16 inch or .300 tongs.
