Modeled after the tennis ball and pen hack, the pen ball holder is a writing aid that provides an extra large surface grip for writing utensils. The tool gently rests on the palm and the resting finger curl position secures it in place, requiring minimal effort and wrist movement to write and draw.
The pen slot is 12mm or 0.47" in diameter and can accommodate writing utensils as large as sharpie markers.
