This is not the same stuff that comes with TBS crossfire receivers. It's the somewhat thicker stuff.
Un-shrunk flattened diameter is 25mm
Fully shrunk and flattened diameter is 12mm
Cut into about 1M lengths
You get quite a lot for the price
This is the good heat shrink, not like the thin stuff that turns into a heatshrink like on a asprin bottle. It stays fairly flexible after being shrunk, and doesnt crack like that cheap stuff. Perfect for individual escs, recievers the size of xm+/nano rx, racewire, and many more.
Very good for small reciver like xm+ or crsf nano durable
