I got mine last Thursday (was ill for the last couple of days). I love them and the quality seems great! I love the artist portfolio idea and well I plan to copy that so THANKS!
I snagged a VERY nice 18x24 artist's portfolio and the Serenity blueprints fit like a glove. It has 24 sheets so I'm thinking of doing some collages of the various and sundry SereniFly paper props in the other pages.
I got it in store, and it came to just under $30 and is worth every penny. The front and back covers are HARD plastic. Each sheet is double sided and comes with an acid free black paper background.
