Rear Mobile Lens Cap (All Series) - Open Box, M-Series

Moment Rear Lens Cap, Open Box — same mount protection, lower price for budget-minded travelers

The gist: An open-box version of Moment's rear lens cap that protects your M-Series or T-Series lens mount from travel dust and grit, at a discount off the new-unit price.

• Same protection as new: Open-box units are unused or lightly handled returns, not damaged goods, so you get the identical press-fit or leash-and-loop protection.
• Series-matched: Make sure you pick the cap that corresponds to your front lens cap's series — T-Series and M-Series caps aren't interchangeable.
• Lightweight and packable: Adds negligible bulk to a camera bag, matching the full-price version's footprint.
• Small savings on a small item: At roughly $8.50, it undercuts the standalone T-Series cap price while covering the same function.

Moment's own product page for the rear lens cap line spells out the series-specific install (T-Series threads through the front cap's anchor loop; M-Series simply adheres), which applies identically to the open-box unit.

Best for: Budget-conscious nomads who already know they need a rear cap and don't mind open-box packaging. Skip it if: you want retail packaging or a guaranteed brand-new seal. Runs ~$8.50 — check the current price before buying.
