I purchased the Tango brand so I could save some money since I lost my Johnson brand Quarter Pin
Stack. There are three main problems with this product - 1) The main problem is that you cannot
fit U.S. pennies into the Pin Stack, which is what most professionals would use (Dimes do not
provide enough contrast) - 2)The Pin Stack is to stiff and shows no illusion of free movement. -
3) The gimmick was dull and dirty looking.
