These insulators are on sale at a great price. The reason they are is there are slight brownish discolorations in a few of the insulators in each pack and as such, we are not able to sell them at full price.

The good news is that after about 3 days in the sun, the insulators turn back white and there is no more discoloration at all. Something wasn't mixed quite right during manufacturing and the funny color happened. Our mistake is your benefit.

Once they are gone, they are gone.

Here is the regular description:
New generation line insulator for permanent fencing with wooden post. Good for polyrope, polywire and smooth wire. Its rounded form and special materials make it resistant to mechanical wear and efficient even when used with the most powerful energizers. Excellent for use with low impedance energizers and high tensile wires.
