Threaded drill pens are the way to go. They hold the tips tightly and securely without the need to use washi tape or tiny rubber bands. I am a hard presser, but with the threaded pens there is absolutely no wobble.
I also really like Diamond Art Club tips because they are slim and sleek and give me much more control when I am placing my diamonds. I find DAC tips especially good when placing squares.
My issue with this pen is that it is short. It is just too short for my small hands. See the photo of this pen next to a standard DAC pen.
Also a side note, the thread screws on DAC tips is longer than the thread screws on all other branded diamond pens that I tried. See the photo of the green pen. The DAC tip will not go all the way in.
I am hoping DAC comes out with a standard size threaded drill pen that I can use with their amazing tips.
