O ring packages
"Should offer both the bigger ones and smaller ones seperately"
I received two different thicknesses
"I received two different thicknesses of the three and a half inch o-ring. As pictured. I want only the thicker ones. I called your office. Apparently that's the way your supplier package is these. The thinner ones do not work properly! Carl 585-978-2053"
