I think there are 6 rings for different sizes and 72 MM is there 

Hi, this is filter adapter rings, support use larger or small size filter on your lens , not related with camera brand. 

FD-EOS fit for Canon FD mount lens and canon EF mount camera body. canon 60d is EF mount, so the adapter ring can work with your camera, but you need to check your lens mount. could you pls let us know your lens specific model? service(AT)kentfaith(DO NOT)com, Please note: It is not same between Canon FD mount and EF mount, this adapter ring is only for Canon FD mount lens, please contact us if you want to purchase for Canon EF mount lens. 

The kit comes with 9 adapter rings for all sorts of lens sizes. You screw the adapter onto your lens, then the square piece screws onto the adapter and the filters slide into the square piece. The lens sizes the adapters fit are 49 mm, 52 mm, 55 mm, 58 mm, 62 mm, 67 mm, 72 mm, 77 mm and 82 mm. It matters more of the lens size than the camera you are using. Have fun with them!! 

Hi, what's your lens size ,this square filter set with 8 adapter rings can fit lens size from 49mm to 82mm, if your lens in this range , it would be ok, thanks.
