The ones I've sent have evidently been dropped really hard. Probably just tossed onto the truck. the1much said some of the ones in the middle of the box were broke! I put them on a few pieces of sheet stryfoam, and they are packed in a bubble wrapped egg carton, with pillow stuffing inside the carton. Plus I put more pieces of sheet styrofoam around the edges of the cartons as a spacer, plus paper or peanuts or what ever I have, but it still didn't work. I think maybe I need to use bigger boxes, or just not ship so many in a box. What would you recommend as the most to ship in a large priority box?
