Frequently Asked Questions
Does the ink bleed through planner paper?
Our premium water-based ink is specially engineered to sit on the surface of most standard papers, preventing bleed-through and smearing, so both sides of your journal pages remain perfectly usable.
Are these pens safe for children to use?
Absolutely. The ink is completely non-toxic and acid-free. They are perfectly safe for school projects, card making, and family coloring sessions.
How do I get the cleanest curve lines?
For the best results, hold the pen completely upright, ensure the roller tip is flat against your paper, and pull in a slow, steady motion. You'll get flawless, unbroken patterns every single time.
