NO!! (LOLOL)

Pack it well in a good box, and THEN PACK IT some more with the first box inside a SECOND box!!

(I learned this years ago when many of us bought used amateur radio gear and test equipment)

That's how I did it in the monopoly sized flat rate box. I packed one inside the other with bubble wrap and whatnot. It made it fine.
