VIBE Pen - Ink Color - Hauser Germany

It appears there may be a slight mix-up in the name: Hauser Vibe is primarily a popular line of extra-dark graphite pencils, while the liquid ink pens with vibrant colors are typically part of the Hauser INX or Hauser Artz collections.  
However, if you are looking for the "Vibe" aesthetic in a pen or the standard ink colors for Hauser products, here is the breakdown:
Hauser Vibe (Graphite Series)
While not a pen, the Hauser Vibe is famous for its extra-dark 2B graphite.  
Color/Grade: Super dark black lead, ideal for sketching and high-contrast writing.  
Body: Features a stylish, triangular ergonomic body often available in various "Vibe" colors (like neon or pastel casings).  
Hauser Pen Ink Colors
If you are looking for the standard ink options available across Hauser’s pen lines (like the XO, Bounce, or INX):
Standard Colors: Most Hauser pens come in Blue, Black, and Red.  
Multicolor Options: The Hauser 4-in-1 includes Blue, Black, Red, and Green in a single barrel.  
Neon/Artz Series: For those seeking a "vibe" with more color, the Hauser Gel/Neon sets offer creative shades like Yellow, Orange, Pink, Green, and Violet.  
Hauser INX (Vivid Liquid Ink)
If you were referring to the liquid ink pens (like the Disney or Spider-Man versions):
Primary Color: These almost exclusively use a rich, deep Blue liquid ink designed for smooth flow and high visibility on school assignments.
Quick Summary: If you want a pen with a "vibe" of many colors, the Hauser Neon Gel set is the best match. If you want the dark "Vibe" performance, that is found in their 2B Graphite Pencils.
