this tool is used to help by storing and assisting in removal of plastic preload clips that go on the shocks of r/c cars. It also functions as a driver for 1/4 hex bits like you would use in a drill or cordless screwdriver and can store up to 7 different bits (no bits are included) It's a great multipurpose tool for trackside tuning when you need to do something, but don't want to walk all the way back to the pits. It's also on a handy retractable leash that clips on, so it's always in reach. Contact me for quantity discounts. please let me know what color you prefer in the buyer notes
