I put in pictures of variety from the past 12 years I’ve known him. Promising review: 'This was a great retro gift for my friend turning 40! He’s very hard to buy for, but he loved this! I ordered seven pictures with the enclosed coupon which I inserted before giving it to him. Uploading the photos is really easy, too, btw! Using that voucher, you place your order for the photo reel, and then they'll ship that to you separately. Here's how it works: You order the reel viewer, which comes with a redemption voucher that covers the cost of one custom photo reel.
I bought one of these for my bestie last year and made a custom reel with some of her wedding photos, and it turned out SO CUTE.
