Good value for money
Bought the set ranging from 20 to 28. They work well for quick spot checks on the production floor. One pen arrived with a slightly loose cap, but the ink hadn't dried out.

Reliable domestic brand
Switched from an imported brand to these domestic pens to cut costs. Honestly, the performance is nearly identical for our standard film testing needs.

Perfect for quality control
Our QC team relies on these Cuiyuan pens. The distinction between different dyne levels is clear, making it easy to train new staff on surface tension testing.

Accurate and easy to use
Very straightforward to use. You just draw a line and see if it beads up or stays flat within two seconds. Helps us avoid print adhesion issues immediately.

Decent but dries fast if left open
The testing accuracy is fine, but you have to be very careful to cap them immediately after use. I left one open for a few minutes while taking notes, and the tip started to dry.

Essential for our packaging line
We use these pens daily to check the treat level of our polyethylene films before printing. The ink flow is consistent, and the results are reliable compared to our lab equipment.
Q: Can these pens be used on metal surfaces?
A: These Dyne pens are specifically formulated for non-porous plastic films, foils, and coated papers. They are not designed or calibrated for testing raw metal surfaces.
Q: Do you offer a bulk discount for purchasing full sets?
A: Yes, we offer tiered pricing for bulk orders. Please contact our sales department directly through the 'Contact Seller' button with your required quantity for a custom quote.
Q: Is the ink toxic or hazardous?
A: The ink contains chemicals typical for surface tension testing. It should be used in a well-ventilated area. Please refer to the included Safety Data Sheet (SDS) for detailed handling and disposal instructions.
Q: What is the shelf life once the bottle is opened?
A: While the unopened shelf life is 12 months, once opened, the ink should be used within 3 to 6 months provided the cap is tightly sealed immediately after every use to prevent evaporation.
Q: How do I know which dyne level pen to start with?
A: It is recommended to start with a pen in the middle of your expected range. If the ink beads up immediately, try a lower number; if it spreads completely, try a higher number until you find the threshold where the ink remains intact for 2 seconds.
