I bought a lot of these for this winter, but it seems I won't be using them as much as I thought, so I'm selling them to someone who needs them. Iris Fine Products, made in Japan Duration: 7 hours Size: 9.6 x 7 cm Expiration date: June 2029 I will ship them in individual packets, taken out of the box. I plan to use Rakuraku Mercari delivery, but I may change to Yu-Yu Mercari delivery. Please understand.
