◎ You can relax and warm up to your core even on cold nights. ◎ The fabric is so soft and pliable that I had to sew it at a low speed on the sewing machine; it feels great against the skin. It's made with a special flannel fabric, a manufacturer's specification not available commercially. ◎ This is a rice bran and brown rice warmer made with locally sourced brown rice from Yamaguchi Prefecture, salt from the Seto Inland Sea, and rice bran. My warmers have an original blend. This rice bran and brown rice warmer warms you from the core, just like an onsen (hot spring). This "from the core" warmth is something you won't find in other warming products. Please experience it for yourself. (It's so soft that I can't take a crisp, well-composed photo! (^-^;) Because it's made of very soft cotton, there may be some brown cotton residue. ◎ My warmers have an amazing repeat purchase rate. Thank you to everyone, always! m(__)m These are sample photos.
