This Alden 74 Bulk Film loader takes 100 foot bulk reels of 35mm film and lets you fill your own reusable cassettes (sold separately.) Why bother? Well, it can save you some money if you're shooting a lot of film- but you can also customize roll length based on what you're up to. Need a 5-shot roll to check out a lens? 10-20 for a quick jaunt around the block? Well, you can do it. Convenient! In excellent condition, with the exception of the film door clips, which are a bit bent. Locks securely when shut, though.
