New Speciality Hot Water Bottle RED Hot Water Bag Hot Cold Therapies U Neck .  This one has a unique U-Shape which works well for neck area, legs, arms, waist, hips and more.   It is a good quality heavy duty rubber type bottle.  It is easy to fill up.  It has a cap that screws on.   Hot water from the tap works great.   I don't recommend boiling water because it is too dangerous to try to put in.   It is a good quality bag.   It is large size - 13 inches across by 12 inches tall.   My children love these.   I fill them up and they will cuddle up to them.   Good for pets too.

I have several styles of Hot Water Bottles Available.  

Thanks for looking!
