It's ridiculous to buy 3D printer nozzle cleaning items if they don't reach the hot end. Push the needle through the nozzle through the hot end and skim off the excess PLA from the tip of the needle. Repeat the process until it's clean. These needles are so short you can barely see them inside the hot end. Totally useless. Made from an expensive material you couldn't save a little extra to make them longer. So my tip is pay what I paid for two cheap tweezers. Just avoid this kit/supplier when looking for cleaning needles until they have the right items to ship.
