Does anyone know of a source for shipping/delivery boxes that fit Hanau/Stratos/etc. sized articulators? Something with an inside dimension of 7"x7"x7" and a top that tucks in work great. The only places I've found that even carry that size or close have a minimum of 100 boxes. I only need about 10-20. Any help would be appreciated. Zahn, Patterson, etc. have articulator boxes, but they are too expensive compared to the box company prices.
