I struggled with purchasing this kistka for two reasons. First - this is a relatively new hobby for me, and second - I wasn't sure that I wanted to purchase such an expensive tip that I wasn't sure that I would actually use. I COULD NOT HAVE BEEN MORE WRONG!
One word of caution - do make the purchase of extra refined beeswax to use with this kistka, or you may find that you do not get the result that you are wanting. It could just be me, but I noticed that in using the standard blocks of wax (the ones with the kistka pictured on them), I had to hold the kistka over the flame longer to heat the wax, which produced a thicker line. After a couple of strokes, I would get that finer line, but only after the kistka cooled down just a bit (again - it could just be me). I did not have this problem when I used ultra refined wax.
I love this kistka! You cannot go wrong with this purchase!
