It is similar to the pressure pointer tool that I bought in 2004.
Seems like a bit of a cheesy website if they won't even show actual photos of the tool..
I can't tell what it is made of- plastic, rubber, metal can't tell...
I decided my pressure pointer was a waste of money, it was not as easy to use as they suggest. The pressing tips were wooden balls of various sizes, firm rubber tips would be much better or some wood and some rubber.
The smooth wooeden ball tips would slide around and not stay where I wanted to press and they were too hard to be comfortable when pressing.
But I do like the pressure pointer's informative website.
*tennis balls, golf balls, marbles and friend or family member with a thumb, knuckle or fingers all work better in my opinon..*
