Finger tips hurt because callusses aren't tough enough to withstand the pressure when pushing on strings.
Build Calluses
To build up tougher finger tips you need to put the pressure and stress on your figer tips daily and as much as possible throughout the day. The more you do it, the stronger your finger tips will get!
Be Reminded
The Finger Tender Ring is made of high quality brass with exceptional detail and texture to give your ring the actual feel of guitar strings. If you bring your ring with you throughout the day, it will be as if you are continually playing your guitar and building calluses the whole time!
