Finding unique colours of electrical tape to mark your gear can be tricky. Then, when you actually get everything marked, the first time you head for Spain the adhesive walks and you get sticky muck all over your gear.
Rack Tags are a good solution. They are fast and easy to apply and have a superior adhesive that withstands temperatures from -40°C to 80°C. They are available in a number of bright colours with a special UV finish to protect the high gloss colour and they are made out of one of the highest abrasion resistant materials available which maintains its colour even when abraded. The rounded ends prevent peeling and the stickers are the perfect size for krabs, wires, cams etc.
