WDT 工具替用針頭

I just got the introvert WDT tool. This is the best WDT tool out there. This tool will last a lifetime! I have to leave a separate review for that tool. And this is why you need these needles! These needles are sturdy but I've already bent a few being a little forceful using the tool. Thank goodness I got extra because I know myself! They fit perfectly and reduce channeling and I just open the cap and replace! These should be bought with every tool. A must have!
