Blisstime 6pcs Rosewood Guitar Bridge Pins Inlaid Abalone Dot Acoustic Guitar Replacement Parts

Do the fit a 1997 Martin HD-28 guitar?

Why does the customer need to ask? Shouldn't the guitar makers and the pin sellers provide the dimensions? Seems like it should be easy.

Do these pins fit Martin OM21 guitar?

Are these 3⁰ degree ??
