Holds a pack of Ryvitas perfectly, either loose or still in a packet if you prefer, though the box states that it is airtight. I have an old Ryvita tin from the 1970s and we've been using that but it's smaller than the modern packs so we had to remove 4 crispbreads before the pack would fit. This box has been a welcome addition to our storage and will keep the crispbreads crisp. The clips are a little stiffer than the usual snap and lock tubs but aren't difficult to use. I'm pleased with it.
Use this every day for our Ryvita. It doesn't fit a whole packet - you have to eat one crispbread (with the new size) before the packet will fit in, but we keep the packet in place and use the box to ensure that it really is kept crisp. Much better than anything else we've tried
