Save your money and time. The felt tip pen clogs and paint doesn't flow properly. Contacted customer service and was sent a number of steps to remedy the issue. Nothing worked. Was asked to send numerous documents, including pictures, which I did. Finally, was told 45 days had passed and nothing could be done. I'm stuck with paint in a pen with a defective tip that can't be used. Customer Service needs a refresher course on how to treat customers. I should have read the reviews before wasting my money.
