I crocheted this using MADE in JAPAN yarn purchased from Seria, which is 95% cotton and 5% polyester, perfect for spring and summer. It has a subtle sparkle from the glitter thread. It does not have thermal insulation. The photos show a 0.48L water bottle and a 600ml plastic bottle inside. Hand washing is possible. The dimensions when laid flat are: Height x Width = approximately 17 x 10.5 cm Bottom diameter: approximately 8 cm Handle length: approximately 24 cm Thank you for looking.
