Really nice Hot Water Bottle.
I bought 2 of these .  One for myself and one as a gift for my bestie and we absolutley LOVE them.  They have a really nice seal, so no worries about leaking.  Really good quality and retains heat for a long time.  Perfect size, and is really nice and flat when not in use.  Great for that time of the month, or headaches.  Highly recommend.
