Instructions are on our 'how to make a lead video' which can be found on our home page, there is not a collar video specifically, but the steps needed are in the video. Collar Kit Includes: 4 split and beveled standard color kangaroo laces (including foils), core of your choice, 2oz of conditioner and 2 welded steel o-rings. Core: 550# test Ultra High Molecular Weight Polyethylene Fiber(HHMWPE) *Note all 4 lace colors at checkout If you need a lead kit, clip or tools, they are available in my shop under show lead supply. *custom color upgrades are no longer available for lead kits, as it takes the same amount of set up, time and clean up as making a 10m section as it does each lace and is no longer feasible. If you prefer custom colors, you can order them rather than the lead kit and have it beveled and split. 10m of lace can make an approximately a 40"+ lead to give you an idea.
