Shipping box question

It’s time for my Sterling HH to move to a new home and free up some funds for a new purchase. A while back, I sent my bass to EBMM to fix something I did; not a big deal but I wanted it done right. They shipped it back in a box that perfectly fits the EBMM case. No room for movement or additional padding. I’m planning to use this box, but I’m a little leery of shipping the Sterling in a box w/no padding. However, I’m thinking that if the guys at San Luis Obispo thought it would be fine, I should too. Any thoughts?
