ERCENTURY Water Brush Pen Set (Length: 6.1 inches), Refillable, Leakproof for Watercolor Painting & Lettering, Set of 4, 1 Flat Tip and 3 Sizes Point Tip Brush Pens Are Available

It's the first time I use a product like that and I'm not very impressed, when you clean the brush the dirty water get stuck inside making the clean water in the pipette dirty as well, plus you can see the colors getting stuck between the pipette and the brush, I'm not a fan of that. I put them aside to use normal brushes.

I noticed in the reviews that some people were saying that they were difficult to take apart and put together again.They unscrew and then re screw up in the opposite direction how we usually do things.Once you realise it’s simple!

They worked fine for me. Please note the barrel has left hand thread so unscrews in a clockwise direction.

Nice pen ,nice price

Use for feeding baby bats. Brilliant for the job and not blocking up as much as previous owns. However. The thread is opposite to what you’d expect so took me a while to figure out why I couldn’t assemble them.

I love these products. I love how practical they are for water colour paintings. Instead of having to use two glasses of water to clean and wet paper I only need to use one jar for cleaning the nibs as you can just give the brush a squeeze.The only reason I rated the ease of use lower was because one of the brushes bristles were a bit wiry and strung out a bit, however i have replacement brushes to use for that unless I can fix it. Very quick delivery also!

Bought these for my 10 year old daughter who really loves painting. She mostly likes to use these with her watercolour pencils. They are handy to use, especially as my daughter has been using them outside in the garden and doesn’t need to have a separate pot of water.They were a bit awkward to unscrew to fill up with water initially, but we soon realised that they twist to open the opposite way to how you would expect.

Wonderful set of brushes which are proving to be transformative to my art practice
