This is an Igusa (rush grass) cushion. This item was previously manufactured at my family home in Okayama and has been stored in a warehouse for a long time. I am now selling it. The Igusa is domestically produced, using either Kumamoto or Okayama-grown rush grass. Quantity: 1 Size: 55cm x 55cm Due to long-term storage (over 10 years), there may be some fading, discoloration, and stains, but there are no issues with use. Please understand this before purchasing. We will clean the stains as much as possible before shipping. There is no box for shipping. It will be shipped in simple packaging with a plastic bag and cushioning material.
