@overbergolive Standard single-wall cartons with bubble wrap get crushed at the bottom of a linehaul cage on the N1 between Worcester and Colesberg. Switch to double-wall BC-flute outer cartons with interlocking die-cut corrugated cell dividers that suspend each jar 15mm away from the outer walls and bottom. Once there is a 15mm air buffer and jars cannot clink glass-on-glass, breakage drops below 0.3% even on economy road freight.
