This is a custom-designed rear lens cap that features an easy-to-see 2-color embossed top. It makes it much easier to identify the correct lens when inserted front down in your camera bag or case.
We designed this cap ourselves and it is not available from any one else. Produced to order here in Seattle using premium polymer.
Shipped worldwide with tracking, typically the following business day. We make custom rear lens caps for all Canon RF L-series lenses. Additionally, we make custom front caps for large telephoto / zoom lenses so be sure to take a look at our other listings.
