CNC cut 1u flat keycaps with square sides. Keycaps are hand finished and coated with your choice of clear shellac, boiled linseed oil, or butcher block finish (beeswax and mineral oil). Sides measure 18mm square, matching the bottom of most keycaps and allowing 1mm spacing between keys. The height is 10mm by default, which will match closely with the top row of OEM or cherry profile caps. Other heights are available on request to match most profiles.
