Existing solutions for neatly and securely storing Allen key sets often make picking them out awkward and difficult, Wiha's ProStar holder is different. Simply slide the holder to have free access to the keys, which can be quickly removed thanks to the tilting mechanism. An internal locking device prevents the keys from falling out when the holder is closed or open. The coloured Allen keys can be quickly and easily identified and, thanks to the phosphorescent paint, are easy to find even in the dark with a UV light. The hexagonal ball head allows easy screwing at an angle of up to 25°.
