I have used a lot of products for many years and this helps with my pain more than any medication I have had prescribed as a pill!!!I have extreme case of fibro and have had it for 55 years so I was just about to give up, this product has given me a new leaf on life...:) thank you LaMota Rockaway Oregon for having these "true north" pen refills available I love your store and sooooooooo happy you are in town
