STAEDTLER Lumocolor Permanent Special Markers Transparency Pen 319F Set Of 3Red

Needed these to safely mark on coated eyeglasses. Got the job done. Thanks.

Enough said. My place of employment buys wax pens and I chose to spend my own money on these because they are the best. Red color is super satisfying for misaligned seg heights (or maybe that's just me lol). Will buy again always.

We got these to mark up our glasses in our eyeglasses shop. I usually purchase from an optical specific place but these did the trick when we needed some fast.

Exactly what I needed to mark lens. Red is sharp. Easy to see. Smidge free.

Great for marking lenses with anti-reflective coatings

The ink runs dry on these a little too soon. I thought it should last a little longer than it should, even though I use it sparingly for my daily tasks as an Optician.

Works great on AR treated eyeglasses. Nice fine tip for accuracy.

I work in an optical lab have been using these for 13+ years. They work well to mark up AR lenses. For those that think they are not working or are dried out, store them tip down for a bit, then try them. Sometimes I will give a slight push down on the tip to get it started.

I bought these for marking lenses with a slippy MAR, and they are the only pens I have found that work for this.
