Hi Guys, I wasn't certain where to ask this, so I figured I'd try here ? Is there any particular ryme or reason why I'm finding Slip 2000 EWL available with both Red & Yellow colored Labeling ? I've always used another product, but Slip does appear to work quite well, so I'll give it a try. But why the different color Labels ? Are some older stock, or ? Any input will be appreciated, THANKS

Best, Dom P.
