Essential for our printing line

This Dyne pen has been a game-changer for our quality control process. The range from 18 to 105 covers all our substrate needs, and the refillable feature saves us money in the long run.

Reliable and durable

We have been using these pens for six months now in a harsh factory environment. They hold up well, and the felt tip remains intact even after hundreds of tests.

Good value, accurate results

We use these for testing laminating adhesion. The results are consistent with our lab equipment. The only minor issue is that the cap can be a bit tight sometimes, but it ensures the fluid doesn't dry out.

Perfect for glue coating checks

High capacity and very reliable. We tested it against other brands, and the USA A.shine pen provided the most consistent bead formation on various plastic films.

Solid tool for industrial use

Works well for detecting oil stains before processing. The wide range means we don't need to buy multiple pens for different materials. Delivery was fast too.

Refillable design is a plus

I appreciate that this is refillable. It reduces waste and lowers the cost per test significantly. The flow rate is smooth and easy to control during application.
