I have sent a bunch of electronic things through the mail (from Japan to Australia) including batteries and have never had a problem with everything arriving. I had them already packaged and when they asked me to write down what was inside the package I put computer accesories or souvenirs or something. However I did have a package sent to me in Australia from someone in Japan and it had a wooden souvenir stolen out of it. I say stolen because it was supposed to be a set of three and the other two in the package were fine so it couldn't have been an issue with the wood etc. It isn't a security risk they are worried about, it is because they are classed as dangerous goods, which is BS as there isn't really any evidence to support that these types of batteries pose any threat when not in use. Also keep in mind all the Ebay sellers in Hong Kong that send batteries (notebook, phone and everything else) to Australia. As far as the wax goes is it really worth the cost of sending it over? I imagine it will be reasonably heavy for the amount of wax you get and therefore relatively expensive to send.
