A unique portable water brush! It's so convenient for quickly pulling out of your pouch and adding some watercolour to your Bullet Journal.
It has a water tank that you easily fill up and squeeze gently to wet the bristles.
Recommended to use with: Archer & Olive or Leuchtturm1917 bullet journal since they both take watercolours quite well!
Koi Water Colour Brush - Small
This is a small size water brush from the popular brand, Koi, that's good in quality and the correct size for using in Bullet Journals.
Can be used with any brand of watercolours. I've used it with watercolour pans with great results in my BuJo!
