I recommend the craft design - Scrapbook Organizer. I have actually had mine a few months and really can't remember where I picked it up.
I put the pictures in that I want to scrap. I sort them using the dividers.
I use the other row to sort and organized my glitters, flowers and other embellishments that come in bottles or containers.
The top lid also flips open for extra storage. I put my layouts and other finished projects in there to move them from crops back to home.
I bought this thinking it would be like my old Cropper Hopper photo storage case. I was wrong, it is BETTER. My old one was double sided so you had to flip it over to get to one side. This one is one sided and nice and deep when compared to the other one. Now if they could just make one just like it but just for storing 12x12 pages that are completed but not in a scrapbook yet I'll be set.
I bought one of these when I first started scrapping and I must say that it is very versatile. The plastic pieces can be moved to customize the storage space or simply removed completely to hold paper envelopes (the center is also removable).
It locks tightly, so nothing will fall off.
It is not as portable as a tote, but will carry a whole lot more than the average bag, so it is perfect for people like me who have a hard time deciding what to bring to crops.
