★★★★★ Customer Feedback (Amazon.com)

★★★★★ – “High quality – Nice high quality tool, took just a few seconds to get the hang of engraver. Would recommend this product.” – TLCobb, January 28, 2025

★★★★★ – “Easy to use – Nice packaging and quick delivery. It took one minute to get the hang of the engraving pen. I’ve tried stamping alternatives and this is so much easier and faster. By far the best value for money, as you get three plates.” – Thomas, September 11, 2024
