I purchased two of these for my Spellbinders Nestabilities sets. I was able to fit 5 sets in each with room for 2-3 more in one of the binders. The binders are heavy, thin, and the flat the closes up the binder is secure. The binder comes packaged with a thick piece of solid cardboard that is going to be perfect to make a book with my new Zutter Bind-it-All (hey, you gotta recycle!) As my nesties collection grows, I am sure I will purchase more of these! The only negative I have about these is that I wish I could find the white ones and I wish there was a way to label the contents.
I have purchased 8 out these because I have a ton of QUickutz metal backed die cuts. And because of it, I bought 2 Nesties and I agree, the storage is amazing, the quality high!! I keep the cardboard in the middle to make sure the dies/nesties don't transfer to the other side when closed... and every bit of protection helps! I managed to get these at 1/2 price from another vendor, but they seem to have disappeared so I will order from here when they show up!
This magnetic storage book arrived fast and was well packaged. Communication from seller was good and customer service was excellent. Book holds a lot of scrapbooking dies and I found it an excellent holder for my quickutz spotlight alphabet. Will buy from again and highly recommend this product and seller.
