Sänger GUMMI-WÄRMFLASCHE

One-Piece Moulded Hot Water Bottles Product with no bonded seams at the neck. Our technically new developed hot water bottle is constructed from a single piece of rubber. The neck piece is now moulded integrally with the bottle walls, instead of being bonded. This makes the Sänger rubber hot water bottle a truly one-piece moulded, water-tight product.
