Heat shrink Tubing 1/32" to 3/64'' diameter for tail and tiny wires

Polyolefin heatshrink tubing for Walkera brushless motor, it is 1/32" to 3/64'' diameter. Small enough to tighten up and protects the tail motor wires solder points and brushless main motor connector solder points. There is a more readly available popular 1/16" diameter heatshrink tube in the market but it does not tighten the tiny motor connection points properly.
