Purchased 100 12" x !2" boxes to pack a large LP and CD collection. Delivery was under 48 hours via Yode, although it was late evening. They came in four packs of 25. The quality of the double-walled cardboard is excellent and they make up into a very sturdy box. The problem is there is zero tolerance in the sizing and fitting a 12" LP in its cover is extremely difficult. It's easier to pack the LPs before taping the base of the box as that allows them to fill the space without damaging them. It's especially annoying as these are advertised and marketed for LPs. If you have box sets it's even more of a problem. So while not ideal, they are good value. Such a pity that they aren't 5mm wider.
