This is a very simple but effective tool set that will help you remove a stubborn filter from a lens. They do this by giving an even grip around the filter and adding extra leverage safely.
They come as a set of 2 wrenches (they are both the same size) so they are compatible with thin and thick framed filters
Please make sure you are ordering the right size.
Size: Suitable for 48 mm - 58 mm Filters
