This is a small tool designed to press on the pressure points used in hand and lower arm acupressure. I used PETG as it has some flexibility to it. There are a variety of ‘illnesses’ that may be relieved by using these pressure points. The following website has more information on where and how to use acupressure (I have no affiliation with the site or the author): https://gokanjo.com/blogs/your-life-relieved/pressure-points-for-arthritis-in-fingers?srsltid=AfmBOooD4MsJ7yAJihS502caVU-ScKVcdF6O0ChPlZnPWmgXLN8IaZsw

NOTE/DISCLAIMER: There is no verifiable medical evidence that acupressure  relieves or eliminates any medical issues. This device is not intended to replace proper medical care. Please check with your physician for all medical issues.
