These packs are filled with flax seed and lavender. They can be heated in a microwave or chilled in a freezer. They will retain their warmth or chill for hours. The neck wraps and packs are great when heat or cold is needed for injuries and sore muscles. They work a little better for children than ice packs. They also are nice to warm your bed in winter and cool it in the summer months. Where a tutorial is available a link will be provided.
