ArtBin Semi Satchel Portable Craft Organizer with 3 Dividers - Clear Plastic Storage Case for Art & Craft Supplies...

It is helpful that this product has dividers, which makes my organization much easier to categorize. Strudy unit.

Very happy with this purchase, greeting cards were taking over the table.

I'm actually using this to store the parts of my food processor attachment for my Cuisinart mixer. It's larger than I expected. I don't know how it would work for craft storage, but I imagine very well. The partitions insert securely and there are four spaces (three inserts) that are about 3 1/8" from one spacer to the next on the two middle compartments. There is a 1/8" space between the top of the partition and the lid, so things may slide to the next compartment even when the lid is secured, depending on what you plan to put in this. It "locks" securely with the latch. It's not airtight or waterproof by any means, so if you need it to be, for some reason, this is not going to work for you. There are rather large holes where the handle attaches which could allow dust, insects or moisture to get in. The lid is attached by an enclosed hinge that seems sturdy. There are also built in "feet" on the end opposite the handle, so you can set this on end without it tipping over. This would hold 4 X 6 to 5 x 7 photos easily. The interior dimensions of the functional space are 7 1/4" W X 13 3/4"L X 6 1/8" D. By functional space, I mean that while the interior dimensions are slightly larger, the inset for the handle and the hinge of the lid, mean that there is empty space in the corners that you can sort of see in the picture. While you might be able to use those corners to tuck other supplies, it will limit how many cards or pictures you are able to store. With all the spacers in, the compartments are 3 1/8" from one spacer to the next, excluding empty space in the corners of the front and back compartments. The bottom edges of the compartments are slightly rounded, but not so much that it would prevent you from storing cards or photos up to 7". Overall, it's a well built tote. Well worth the money I paid for the use I intend. There was a "cut" on the bottom of the tote that I received (probably from a box cutter when someone opened a bulk package). Since the cut doesn't go all the way through and my use is probably going to scratch it up anyway, I'm not too concerned. Might bother some people though.
