Airweave Pillow Slim Purchased in November 2023 I didn't use it much after buying it because it didn't suit me. A warranty card is included, but the warranty period has expired. I will also include a Rakuten-purchased silk pillowcase (worth 4,480 yen). It will be shipped in a simple, folded package.
