Authentic USA original
I was worried about getting a counterfeit, but this is definitely the genuine A.Shine product from the USA. The build quality and ink performance are superior to generic brands.

Essential for our quality control lab
We use these pens daily to test surface energy on plastic films before printing. The results are consistent and match our laboratory standards perfectly. Highly recommended for industrial use.

Good product, fast shipping
The pen works as expected for checking corona treatment levels. The only reason for 4 stars is that the cap can be a bit tight sometimes, but the ink flow is excellent.

Works well but pricey
The pen functions correctly and gives clear readings, but it is slightly more expensive than other options on the market. You pay for the brand reliability though.

Reliable for packaging tests
Our packaging team relies on these for adhesion testing. The German standard compliance gives us confidence in our export documentation. Will order again.

Perfect for coating analysis
We use this for analyzing coating uniformity on various substrates. The tip durability is impressive, and it hasn't dried out even after weeks of intermittent use.
Q: Can the ink be refilled once it runs out?
A: No, the A.Shine Dyne Pens are designed as single-use disposable units to ensure the accuracy and purity of the test fluid. We recommend purchasing a new pen once the ink is depleted.
Q: Is this pen suitable for testing metal surfaces?
A: Yes, the A.Shine Dyne Pen can be used on treated metal surfaces to verify cleanliness and readiness for bonding or painting, provided the surface is free of heavy oils.
Q: Does this come with a certificate of authenticity?
A: Yes, as an authorized general agent product, each unit comes with documentation verifying its origin from the USA and compliance with German standards.
Q: What is the specific dyne level range for model 21-72?
A: The model 21-72 typically covers a specific range within the standard testing spectrum, often used for mid-to-high surface energy materials. Please consult the technical datasheet included in the package for the exact incremental values.
Q: How should I store the pen to maximize its shelf life?
A: To maximize shelf life, store the pen horizontally in a cool, dry place with the cap tightly sealed. Avoid exposure to direct sunlight or extreme temperatures.
