A good taper pin stays in and is flush enough for shelves to slide back in easily. Great color that appears almost invisible when installed. 300 seems like a lot until you realize how many holes have been drilled. Bought these recently after noticing what looked like round sawdust. It turns out that the cabinet-quality plywood used in expensive carpentry work comes from overseas and comes with dry-wood termites. They love anything that isn't painted - like the holes that get drilled in your cabinets. Bought some thermite dust, blown out the holes, sanded and put these well fitting plugs in the unused holes.
