## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice weight, god quality and works on my MB 149 fountain pen
*by A***R on March 18, 2025*

Works as described and allow me to take apart my Montblanc 149 fountain pen and readjust the piston filler (only) that the MB service center failed to do correctly.

### ⭐⭐⭐⭐⭐ Works as intended for the P136. Durable.
*by R***W on December 3, 2023*

This wrench works as intended, and it's metal so it's more durable than common plastic wrenches. Because the P136 is partly an imitation of the Mont Blanc 146, some people say this wrench will work on the Mont Blanc as well, but I can't personally confirm that. If it's true, then this is an inexpensive way Mont Blanc 146 owners can service their own pens, because as I understand it, Mont Blanc doesn't supply a wrench and requires the pen to be sent in for warranty work. Even if it's not true, these work well for the P136, and I suspect might work with other pens with similar nib/feed unit dimensions.

### ⭐⭐⭐⭐⭐ Solid tool
*by C***S on June 30, 2024*

Did not fit my Mont Blanc
