This cap features a front pinch style lens attachment, that does not protrude beyond the cap's diameter, rather than the snap-on outside grip style. The center pinch type is therefore much easier to attach and detach when a lens hood is mounted.

Although there is a dislaimer that the images might not match the products, it seems reasonable that this lens cap WOULD include an attachement string as shown. However it doesn't and the initial response from Adorama was so be it. After saying I'd take my business elsewhere they did decide to find an attachment string to send.
