Mother Nature has blessed us with everything we need, yet we wander to find something beyond and beneath. Adri s natural Heating pad is made from a few of such blessings from Mother Nature, in a way that does no harm to her children. The heating pad is made from natural wheat with organic flaxseeds, which are known for not only for effective pain relief but also for providing comfort and warmth. These pads can also be used by putting 1-2 drops of essential oils, which can give added benefits of herbs like Lemongrass, Lavender, etc that will eventually result in releasing its gentle rejuvenating aroma when heated. These pads are durable enough to be used in microwave multiple times and are extremely convenient to use for a longer time. Fabric used in these bags is corduroy. Since this is handcrafted, slight variation in size might be there, we request you to enjoy its uniqueness, rest we have taken care of the quality of ingredients used. Each heating pad comes in a Jute Packaging, please make sure to remove Jute Packaging before putting it in microwave. Make sure not to put in a watery place, heating pad should be completely dry before/after use.
