If you want the TAD Japan will use double packaging method for TAD R1TX, where the outside of the package is packed with another one (Tri-Wall).I'm almost certain that my R1 Mk2 came in a similar cardboard box several years ago. No issues at all, but I agree it was surprised with the packaging. M1s that these R1s replaced were in wood crates.
you can also order wooden box for maximum safety.
TAD Japan carefuly listen to customers feedback and their philosophy is introducing perfect quality.
