Bee Snug is made with a durable canvas cotton and contains flax seed which provides a gentle, moist heat and will retain the heat for several hours. It can also be chilled in the freezer to reduce fever or slight inflammations. It is flexible and can be shaped in any way. It will ease neck tension or keep your feet warm on those cold winter nights! Bee snug has been infused with the aroma therapy properties of the ’Nectar of the Bees’ which includes lavender & chamomile for relaxation; neroli & geranium to alleviate stress; rose & ylang ylang for emotional uplifting and pink grapefruit for youthfulness.
