I used to work for UPS as a kid, putting Fragile on a box is the equivelent of Please bash me repeatedly. You are much better off making sure the package is balanced and not too heavy. oh Make sure the lable is on the side you want facing up. Tape well with no crack or seams that can split
Make sure the box is much bigger than the board if you only have 1" clearance on the sides of the board get a bigger box. REMEMBER FRAGILE=BASH ME. Label ON side you want UP.
Arrows and instructions don't work.
When you have to unloads trucks by hand at the rate of 1480 boxs an hour minimum you don't have time to be gentle. throw them label side up on the belt don't read or think.
except for the ocasional fragile box to take your frustrations out on.
