It's a thin, light blue gauze fabric. I bought it three years ago at Tomato in Nippori. I bought it intending to make a summer sleeper with the cool-touch fabric, but I never used it and just stored it without unfolding it. There are fold marks and some discoloration on both edges and in places. The size is approximately 185 x 145 cm. Please note that there may be some errors as it is a rough measurement.
