If it's in response to trying to purchase any of their Transformer toys, they are not able to sell except at specific conventions in Japan due to the licensing agreement with Tak/Tomy. Not sure why they haven't emailed you back though, maybe save for a language barrier.
Justitoys only delivers toys to sellers and distributors so I can't imagine why they would give out their phone number. Its not on their website. I've only e-mailed them once, but I got a reply after a couple days.
Yup.. that's what I get for posting at work when my brain is fried. My bad Devastator X.. Nothing to see here.. carry on... nothing to see at all.
