After finding rip-off prices in my city, I'm looking for online sources to find a decent portable Bento lunch box. I've also been checking Ebay, but a lot of them seem overpriced or of questionable quality from China instead of Japan. I know we have a lot of Otaku fans out here, so hopefully I can get some sources to Japanese online retailers or particular brands or types they recommend. Other English websites like jbox has a very poor and expensive selection, so it's a pretty grim outlook for me. I'm looking for a microwave-safe, 2 or 3-tier layers, of resin and maybe with silver ions to prevent bacteria growth (I saw it on one, I dunno if it really works though). Please no links to Hello Kitty or female bento boxes, lol. Thanks!
