The pages fit great - it takes some time to get the screws off the album (screw head is a K) however these pages fit great and all the additional pieces are included. I switched out the K screw head with the ones provided in this package.
K and Company are my favorite books and refill kits. The pages are always the right size, so you can buy other brands of cardstock and it will always fit.
These page protectors work great for scrapbooking with K&Co albums. I put 40 pages in each scrapbook I make... these are a must!
