Our handcrafted therapy packs are also multi-functional. They can be heated or cooled depending on the type of therapy you are looking for. When heated, these packs create moisture naturally and when used in conjunction with our products they make the products more effective. When heat and moisture lay on the skin, the pores open allowing for maximum penetration. Use before and after applying Super Salvy or Warm Me Up to experience these added benefits! You can also place the pack in the freezer for a cooling pack. These packs are not scented. They come with a case that is hand-washable and they are available in two sizes.
