These sections of metal braided wire loom make for an amazing way to hide and protect wires while looking good doing it. I have been using these in crystal chambers of late when space is too tight for multiple brass or copper tubes to conceal wires.
Just remember, these are conductive and should not be placed right up against a PCBs as they could cause a short. Instead, use then in the middle of wire runs where applicable.
Each listing is for a 4" section. Ex. Most crystal chamber runs I end up using 1.5" lengths, so you can get two at minimum or 4 if you are building smaller chambers.
