Good value for industrial use
Works well for our daily cleanliness checks. The only reason I didn't give 5 stars is that the cap can be a bit tight after prolonged use.

Perfect for oil stain detection
Exactly what we needed for detecting residual oils before coating. The ink flows smoothly and dries quickly for fast reading.
