I can't get any response from RITR on social media, so here's hoping you folks can shed light on this... I recently lost (GAGH, ) a binder containing, amongst other things that have been irritating to loose, both my RITR YE99 and RE99 mechanical pencils. I forgot it was lying somewhere (busy day), and someone appears to have been light fingered, and walked off with it. My fault, I should have kept better tabs on the thing, but that's life, and there are, sadly, dishonest people around. So, replacement time. But I can't find them in stock anywhere, including the RITR website. So, have they been discontinued? TIA for any light that can be shed on this.
