Sakura's Gelly Roll® Classic white pens are the perfect tool for working on both our black and Renaissance Zentangle tiles or even for use in layers over black ink on our white tiles. You will love how this archival white gel ink flows across the paper. For best results, just tickle the paper with this pen. It is amazing how little pressure it takes for wonderful results. Enjoy how you can fill and draw with this pen in your Zentangle art.
