I-DISCOVERY SQUARE FILTER 3 IN 1 KIT ND8 -52MM

3 In 1 Kits This product provides 3 tools at once, namely Filter Holder, Adapter Ring, and Square Filter. You can save your expenses by buying 1 product for 3 products at once. How to use: You can put the Adapter Ring on your camera lens. Then slide the Filter Holder slightly on the adapter ring until it locks into place. The Filter Holder is now attached to the lens, but can be rotated to the right or left. The one closest to the Filter Holder is the one with the narrowest space, it allows the use of Round Filters with curved edges (such as polarizers, Star Filters, etc.). The two central slots are intended for the Square Filter that has been provided.
