Ease your aches and pains with a Spotpack heat pack! Our versatile "original" heat pack features a removable cover, making it perfect for stomach cramps, back pain, and kids' growing pains. Measuring 40cm x 17cm and weighing 1.2 kg, the Spotpack original heat pack is designed with both an inner and outer bag for easy washing and sharing. The inner bag is divided into three sections to ensure the contents stay in place. They are filled with Australian lupin seeds, which are virtually odorless when heated and don't attract weavels like other fillings. They are also safe for those with gluten sensitivities.
