38mm Collar With Large Spikes-Unlined Raw (M2O) quick release and it shows in howA 38mm wide spiked collar in vegetable tanned full grain leather, left unlined for that raw, edgy aesthetic. The large spikes make a statement, and you get to choose both the leather colour and hardware finish black, silver, or brass. The leather's aniline dyed, which means it keeps its natural grain and character. You might see the odd mark or variation in the surface that's the full grain showing through, and it'll age beautifully over time.
