Strange thing is, speaking from a uk perspective, using royal mail it is no more expensive to send one loose figure to europe/usa in a small box than it is to send in a jiffy bag. I'm fortunate that where i work, i can pick up good size small boxes for this purpose. Not sure how it works sending to the uk from abroad, but yeah, certainly anything of any value should be sent in a box or, at least well wrapped up in extra bubble wrap and then put in a jiffy bag.
