When I do a scrapbook, it never stops at the number of pages that come with the book so I am constantly expanding my books to fit my need. These extension posts are the best because, so far, they have fit every book I have had to expand. I have bought others that work with themselves but not with the posts that come w/ the books. The various sizes are a must because you never know how much you need to expand. I highly recommend this product. Oh and the best price I could find is on Scrapbook.com
Came in 3 different sizes. I wish I could just get the larger two sizes, but cheap enough that I'll buy more of these packs just for the ones I use.
Standard thread size, works with the We R Memory Keepers - Classic Leather posts.
Good threads. Not like cheap aluminum ones I've used that are hard to screw in.
