I just got the kit in today and must say that I'm glad I got it on sale for $11.99. The reported retail price of $39.99 suggests to me higher quality in the papers and the recipe cards. The cards are not as sturdy as recipe cards one would buy and the dividers included are the same material--just slightly thicker than paper, but not cardstock by any means. I will probably put the paper and extras in my stash and cover the box with nicer paper.
I have not yet put the box itself together, but I think the quality there is good. If you are interested in making altered recipe boxes, my suggestion is to buy the box only and make your own recipe cards.
