This is a medium hot water bottle, measuring 8.5 inches to the shoulder and 6.5 inches across. The cover adds approx. 0.5 inches, in both directions.
This one has a soft, hand knitted cover in a 50% merino and 50% acrylic yarn in definite, clear tones of blue and yellow. The top is deeply ribbed and turned over double.
The rubber hot water bottle itself is a more muted blue - plenty of comfort and warmth to cuddle up to!
