No wonder they created so much buzz in Japan. JetPens is proud to search out great products like these and bring them to you!

Like many watercolors, the SAI brush colors other than black are not light resistant, so colors will fade if kept in sunny areas. These brushes are perfect for journaling or painting artwork for indoors. SAI brushes are optimally stored horizontally to prevent bleeding from the tip.
