Frequently Asked Questions
Is Keep Smiling brush pen good for calligraphy?
The 1-2mm flexible fiber tip responds to varying stroke pressure. This mechanical flex enables the thick and thin lines required for hand lettering.
Are Keep Smiling markers refillable?
These markers use a sealed internal reservoir system. They don't support external refilling once the water-based ink supply finishes.
