The COOLTOOL from Vello is an easy-to-carry photo and video multi-tool that helps tighten most quick-release plates with a combination of a 4mm hex wrench and a large slotted screwdriver. A large gripping surface allows you to apply plenty of force when tightening and securing your gear, making the COOLTOOL easier and safer to use than a coin. Mount it on your keychain and have it handy when you're on a photoshoot or in the studio.
