This is a lens hood for the SIGMA 18-50mm F2.8 DC DN | Contemporary lens. I am selling it because I am selling the lens. I am also selling the lens body, and will offer a discount if purchased together. Please purchase through a combined purchase request if you wish to buy both. This is the short.ver. When the hood is attached and the cap is on, they are flush. There are no noticeable scratches or stains, and it has been used relatively little. I purchased this from an individual seller on BOOTH. It was 3D printed, and the seams are visible, which is part of the design. The original product page is below. https://booth.pm/ko/items/6985227?srsltid=AfmBOopw9c-4Dnxa5Gep5ptuB0Nz9FautR2b7YjdFULJLJcJ4Sw1dcVU
