I was at a lfs and saw these stunning colored leather fingers, does anyone have an opinion or comment? I am assuming they are not natural, unless rare but for the price they were selling I highly doubt it?! I have heard of FW parrot fish being dyed but live corals as well??? If it is dyed what is the downside, o fcourse the upside is the rare color,....but will color fade, will lifespan decrease et etc.
