There page used to be http://www.pvc-plea.jp. As far as i know, nobody ever managed to order, as they seem not to speak english. Now you can find all their products under http://www.bidders.co.jp/dap/sv/list12/page_I1_Hkeyword_I-83-73-81-5B-83-75-83-43-83-5A_Hsort_Iend_Hst_I2_Huser_I687672_Hsrm_IY. I think this http://www.bidders.co.jp/pitem/92861468 is the model *you are looking for, but I found pink pants with white or yellow seam as well. My prefered model wopuld be http://www.bidders.co.jp/pitem/98770340 (as there is no way to hide when pped) or http://www.bidders.co.jp/pitem/138404639 (additional security with the belt). The product pages seem to be up to date (Copyright 1999-2013) but some still have links to http://www.pvc-plea.jp If you manage to find a way to order please let me know!
