3 row storage boxes for graded cards?

[vintagebaseballcardguy]

Guys, I use the white corrugated storage boxes made for the graded cards in my collection. I own some 1 row vaults and 2 row shoe boxes, both of which accommodate slabs. I would really like a 3 row box for graded cards, but I can't find one anywhere. Anyone know of any? Thanks.

Update: Someone on the prewar side connected me with a seller.

I don't know if they are still available, but I bought some a while back from wkucards on e-bay.
