※ Regarding shipping, I generally ship within 24 hours. It will be the shortest possible delivery time without specifying a date and time. This is a special collaboration product with a chiropractor: the Brain Sleep Pillow Stretch (a pillow for stretching while you sleep). The size is approximately 600mm wide x 360mm long x 100mm high. The pillow cover has been washed, but if you are concerned, please prepare a new one. I have used it a few times and stored it at home, so please refrain from purchasing if you are very sensitive. I plan to ship using recycled packaging materials, so please consider this only if you are okay with that. Negotiations for price reduction are not possible. No comments needed, instant purchase is OK.
