GLS as its free, i always order quite a lot and the litter is always on the verge of busting out and the tins are always put loose in a box thats too big for them so its likes 10 peas being shaken around in box
90% of tins are always dented.
When i ordered bozita in cartons i would often have a burst one leaking juice all over
ONCE i received my tins in their original packaging, this reduced almost all dents as they were clingwrapped on trays in 6's or 12's, its never happened again
