I ordered those Martin pins for my 000-18 Reimagined to replace the cheap plastic ones. The choice of Martin original pins versus other cheaper alternatives (like Harley Benton) was driven by the exectation of a perfect fit.
Instead, the pins were larger than the originals and I had two alternatives: drilling the pin holes or sanding the pins. The first option was better from a technical point of view but not reversible so I went for the second option. It took me 2 hours to sand them down to fit the holes properly.
The final effect was very good, visually and sonically but I expected a better fit for a product paid 35 euros.
