I purchased this from MUJI about 4 or 5 years ago. I used it for about a year to hold receipts and cash for household budgeting, but I couldn't get the hang of it. I bought a total of 7 refills, but upon inspection, I had to discard 3 because the seals wouldn't close. The 4 in the image close after being opened and closed 4 or 5 times, but two of them don't seal perfectly. However, they close if you press on them with your finger. Please be aware of this. It's a gray nylon multi-case with a zipper and clear pockets. - Color: Gray - Material: Nylon - Number of pockets: Multiple - Accessories: Clear pockets - Closure: Zipper Thank you for looking.
