The Tiger Onyx LTD is made with the same Bore hide as the Tiger Sniper tips. Each of the finest layers are then collected and aged with Tiger's own secret process, turning each layer to black without using a black color dye. During this process, we are able to soften the layers to medium hardness, while making the leather firmer. It makes the tip easy to maintain and helps to cut better during repairs. Onyx - LTD is the most consistent by far of any tips made. It will only be produced in limited numbers per year. Purpose of the third red color layer from the bottom is to warn you when it's time to replace the tip & cosmetically make the Onyx-Ltd tip different than any other black color tip. This single tip is 14mm and are sold PER tip.
