Wicking needles for candle making - YouTube

For sale is one 10.4” long stainless steel wick threader, the best wicking tool that i cannot recommend more.

*** This is actually not a needle although the manufacture calls it a needle, it's a wick threader with a hook, if your mold doesn’t have a hole, you still need a needle to poke a hole first before using this hook for threading your wick.

*** Works wonders with all types of silicone molds except the long tapers and very big pillars ( as the it’s only 10.4” long and the hook is small which may not work well with big wicks)

*** Works especially well with small /mini tapers and small to medium sized molds.

*** This one is my favorite wicking tool that I personally use all the time, it’s designed with a hook to help get the wick through the wick hole, and the circle at the end is easy hold to pull. made with stainless steel, it’s slim and strong, won’t make a big hole on your mold, perfect for shorter taper molds, mini taper molds, small to medium pillar & votive molds.

*** The flapper- the latch design ensures your wick stays in place.

** * Size: This long loop hook is 10.4 inches long and has a width of 0.98 inch at the small ring at the end.

*** Applications: it is perfect for a variety of crafts, such as button loops, closures, candle wicking, string belts, and more. it definitely helps improve your entire crafting process.

*** It may or may not work with metal molds which depends on how big the wick hole is.
