Fast shipping
Needed specific dyne levels urgently for a new client project. These arrived in two days and worked exactly as described. Highly recommend for industrial use.

Reliable and affordable
Switched from a more expensive brand and noticed no difference in accuracy. The tips are durable and don't fray easily even after hundreds of tests.

Essential for our QC lab
We use these pens daily to test adhesion on packaging films. The ink flow is consistent, and the results match our lab equipment perfectly. Great value for the price.

Good range of options
Ordered a full set from 30 to 60 dyne. They work well for quick checks on the production line. One pen arrived slightly dried out, but customer service replaced it immediately.

Solid performance
The color contrast of the ink makes it very easy to see if the surface wets properly. Only minor issue is the cap can be a bit tight sometimes.

Perfect for printing prep
As a print shop owner, ensuring surface tension is critical. These pens are accurate and the low price allows us to keep fresh stock on hand without breaking the budget.
Q: Do these pens come with a calibration certificate?
A: Yes, each batch comes with a standard quality control report. Individual calibration certificates can be requested for an additional fee.
Q: Is the ink toxic or hazardous?
A: The ink contains formamide and other solvents. It should be used in a well-ventilated area. Please refer to the SDS (Safety Data Sheet) included with your shipment for detailed safety information.
Q: How many tests can I get from a single 10ml pen?
A: Depending on the length of the stroke, a single pen typically provides between 300 to 500 individual tests.
Q: Can these be used on metal surfaces?
A: These pens are specifically formulated for non-porous polymer surfaces like PE, PP, and PET. While they may show wetting on clean metals, they are not calibrated for metal surface energy testing.
Q: What is the best way to store these pens to maximize shelf life?
A: Store them horizontally in a cool, dark place between 5°C and 25°C. Ensure the cap is tightly sealed immediately after each use to prevent evaporation.
