### ⭐⭐⭐⭐⭐ It works correctly with my Stadler pen set.

works like a champ.

### ⭐⭐⭐⭐⭐ Very nice
*by C***N on May 24, 2025*

Very recommended, my best best silver inking method

### ⭐⭐⭐⭐ Liquidraw or Technoart?
*by A***R on July 25, 2025*

Box says Liquidraw as brand, but bottle says Technoart. Probably the correct product because both have a similar crosshair emblem, but strange nonetheless.
