Box Packing

We have recently had a phase where the customer as done a self pack up and not taped up the boxes properley especially the bottoms.... and when they are full of heavy items  the bottom just gives way and crash lots of breakages !   ..... you need to tape at least 4 inches up the side of the boxes with proper parcel tape.....also do not put anything in boxes for us to move that is of sentimental value or is irreplaceable to you please take all these kind of things yourself
