At wigzi they produce each retractable leash with stainless steel rustproof technology. 10% chromium is added to prevent rust, so you can walk in the rain with peace of mind. The internal retractable spring is precisely adjusted so that it fully extends up to 5 meters and fully retracts to the rear with ease. This is the result of many years of development and testing.
Each product is designed to make dog walking fun and reliable for years to come.
