* one pair of pins is already included with each Patient-side equipment shield. So there's no need to purchase these unless you need replacements/extras.
These are improved mounting pins for chin rest papers as well as the new Px-side breath shields.
They are printed with FormLabs Durable resin and can be soaked in IPA.
The knurling makes them easier to grip and they will hold more tightly than the pins that come standard with most slit lamps.
