While we’re pleased to know you were satisfied with the pen’s design, stylus function, and imprint quality, we’re truly sorry to hear about the issues you’ve encountered with the ink performance. That’s certainly not the experience we want for our customers. To help us investigate this further, please reply to this email with a few photos or a short video showing how the pens write on paper. This will allow our team to assess the concern accurately. We appreciate you bringing this to our attention and look forward to your reply.
