These extra tips work great. I put them in the wood burning tool I have have and work away at my craft projects. There are 15 wood tips ( silver ones) and 10 soldering tips ( golden ones) and a hot knife attachment. The hot knife is great for cutting things like styrofoam and rubber and plastic. THe soldering tips can be used on the wood also. There are stamps and fine tips and wide tips and circles and dots. There is also an alphabet stencil. #rankboosterreview #Sponsored #OLOGYMARY https://www.amazon.com/Stencils-Soldering-Pyrography-Alphabet-Personalization/dp/B0776P99LY
