That is pretty much the way the painter sent my icredibly delicate coke-can scandium frame back after polishing and powdercoating it. Nah wait, he put he frame in a transparent plastic sleeve (giant size), then put it into the cardboard box. It arrived in imaculate condition.

My worst experience with bike packaging: I once had a classic (Rabeneick Campagnolo) sent to me, it was an ebay deal. it came practically as it was, apart from two pieces of cardboard on both sides. The sticky tape used to keep the two cardboard sheets together and on the bike were put over the top tube decals, which promptly came partly off at removal.

On the other hand, i once had an almost NOS KOF frame shipped from Chicago. The seller, whom i had met at the CR list, had done the best job ever to pack the bike. It had old axles between the dropouts, and every bit of the frame was covered by formed foam parts. It took me the better part of an hour to unpack, and must have taken the seller hours to pack it...
