Reliable German engineering

The babtest pens are the industry standard for a reason. Precise measurements every time we test our corona-treated surfaces.

Great variety pack

Buying the set with different dyne levels was much more economical than buying individually. All three brands represented here are trustworthy.

Good value, fast shipping

Ordered the Cuiyuan set for lab testing. They work well for general checks. The only reason for 4 stars is that the cap feels slightly loose on one of the pens, but the ink quality is fine.

Essential for our printing line

We switched to the A.Shine ACCU pens for our packaging line and the consistency is excellent. The ink flows smoothly and gives a clear read on our polyethylene films.

Decent but dries out if left open

The pens work as described, but you have to be very careful to cap them immediately. I left one open for a few minutes and it seemed to lose some potency.

Perfect for quality control

Our QC team uses these daily. The distinction between wetting and beading is very sharp, making it easy for new operators to learn quickly.
