WHICH OF US HAS NOT EXPERIENCED THIS LITTLE ANNOYANCE?

You’ve just soldered two wires together, only to find that
you’ve forgotten to fit the heat-shrink sleeve. Our new solder sleeves consign this problem to the past!

Simply strip the insulation from the two wires, slide the bare ends into the sleeve, and heat with a micro gas torch or heat gun until the solder in the tinned ring runs: the two wires are now reliably soldered together!

Job done!
