I have no idea what you said but, This stuff is good, shrinks with a cig lighter, and cost's 25cents a meter, great for motor connections and battery plugs, I use this as order fillers, great stuff great price!!
**** = I place up a few Buddy Codes for other people to use. Admin (?) removed them but I still see other Buddy Code on a few items. I use a hot air gun to shrink the tubing that my wife uses for embossing.
Great shrink tubing at a very low price. The 4 mm size works great for covering splices on motor and ESC wires and for covering the solder connection to gold bullet connectors. I ordered both red and black. It shrinks easily and looks and works just like the expensive products from local sources.
