Independent Lab Proves that not all UV Baseball Holders are alike
KIPTON, Ohio -- March 18, 2008--An independent lab tested both the Pro-Mold UV baseball holder and one from another leading brand. The results show that the Pro-Mold holder is 25% more effective at blocking out stronger ultra violet rays. The results of this test from the Akron Rubber Development Laboratory are below:

Discussion
Ultraviolet light is divided into three major wavelengths: UVA, UVB, and UVC. UVC radiation is completely blocked by the ozone layer with wavelengths from 200 to 290 nm. The UVA and UVB radiation is not completely blocked by the ozone layer. The UVA wavelengths are from 320 to 400 nm and the UVB wavelengths are from 290 to 320 nm.
