This bag is knitted with extra-thick cotton yarn. The color is navy, and a magnetic button is attached to the opening. The wide opening makes it easy to use, and the plump form is cute. Because it's cotton, I think you can use it regardless of the season. ***Size*** (Measured flat) Opening: Approximately 24.5cm Bottom: Approximately 16cm Depth: Approximately 19cm Handle length: Approximately 30cm Knitting yarn: COTONE 60% cotton, 40% acrylic #handmade #ecobag #grannysquarebag #pouch #seasonless
