I've searched far and wide, and couldn't find anything that even comes reasonably close. This is an extremely well crafted, compact and portable strap storage solution. The large folio is exactly what I needed for my 50+ straps. The materials are excellent and the design is flexible. I'm a fan.
I have a lot of straps and finally have found this “book” to store all of them. The folio is sturdy and well made. The leather is good and the lining inside is a nice contrast. Can fit 72 straps and happy to mark them with the given sticker.
