From the general picture in the "trays and storage" page, what they offer mightbe the tougher plastic which has the diamond on top, which was described previously with a top that was either caving inward or puffing outward.
I'm not convinced they are the flexible plastic type.
Thanks Chase but it looks like the ones you have are not the same as the ones smore has posted...I've got the kind with the diamond on top and they are not soft or flexible and that's what makes these desirable. But you may want to head over to the M2M forums and post your boxes as I'm sure someone will snatch them up.
