Review on 🎨 UPINS 12-Piece Set: Watercolor Painting Markers for Vibrant Artwork by Kristen Simpson

I found the threading mechanism to be weak and the tips of the brushes did not rotate up and down equally. what seems like a trifle - if you know it beforehand! If not, you'll end up twisting and twisting the top of the brush thinking it's just stuck until the thin, flimsy plastic is permanently distorted. I had a new idea of turning the brush the other way and it came off, although not as easily. The fact that some require you to turn left and others to turn right is something of a nightmare and design flaw. You'll never remember which are which until you mark them with permanent marker. I also found the bristles to be very cheap and break easily. This isn't the first time I've bought this type of brush and I know how to use brushes. Wouldn't buy again.
