Review: Another good watercolor brush for my collection. - Another good watercolor brush for my collection.
Review: I wish that I started with this brush! - The right brush matters when you're beginning and the Princeton Neptune blew me out of the water. I wasn't so sure at first because of how soft the bristles are, but what do I know, all of my paint brushes are sub mediocre compared to this brush. I have practiced enough to test it on my Academy 100% cotton watercolor paper and feel like I'm finally making progress in my watercolor journey. The way the brush glides nicely over the paper and the brush holds a good amount of water. The rest of the Neptune series brushes are on my wishlist!

## Questions & Answers

**Q: Does this brush work with acrylic paint?**
A: I definitely wouldn’t use these with acrylic. The hairs are very soft and acrylic would probably just gunk them up.

**Q: Is this a short handle?**
A: It is short not as short as a travel brush i would guess 5-6 inches but that is a guess. I hope this helps.

**Q: Is this brush safe to use with glaze for pottery?**
A: Not sure about pottery I purchased for watercolor.

### ⭐⭐⭐⭐⭐ Great watercolour brushes
*by C***R on June 6, 2018*

I like princeton brushes so went ahead and ordered a few of these for watercolour painting since I had read that they can hold a decent amount of water /paint. I have to be honest, at first I didn't like these. There wasn't a whole lot of "snap" to these and if you pressed all the water out the bristles become "stiff", in that they don't return to a centered position when you finish brushing across the page. So it took me a while to get used to how these felt. So now that I've used them for a month or so, I love them and they have become some of my favorite brushes. They do hold a TON of water, and that took some getting used to so I didn't saturate my paper. They are very soft and pliable, they clean up easily and always return to a good shape afterwards. I'm looking forward to ordering more of this particular style to complete my set and hope others enjoy them as much as I do.
