Natural texture. Made with a mix of cotton (85%) and linen (15%), which is absorbent and breathable. Size is 43cm wide x 63cm deep. This is a set of 7, equivalent to 7000 yen when new. I purchased them a year ago and have been using all 7 in rotation, so I think they are still in good condition. I am selling them because I am replacing my pillows. Because of the linen mix, the material is more crisp than soft, and I think it's good for those who prefer a smooth, cool feel.
