A brand born and loved in Germany. In the cold season, fill it with hot water for warmth... In the hot season, add ice for a refreshing experience... It can also be used as an ice pillow. ★ I just bought this, but I am selling it because the size is different. ★ The main body seems to have a slight color change, judging from the head area. Please check the images. Main body: Approximately 31.0cm ✕ 19.5cm Cover: Approximately 32.0cm ✕ 20.0cm ☆ Avoid boiling water; use water around 70 degrees Celsius. ☆ Fill with water to about 70-80%. ☆ After filling with water, gently remove the air and tighten the cap securely. ☆ The included cover is thin, so you may need to use an additional cover or cloth. Handmade covers are also available for this type. ❇︎ Due to compact packaging, it may be lightly folded for shipping. Please understand. Thank you for looking.
