Why You’ll Love It

Spanish ISO Layout

Designed for Spanish ISO keyboard layouts. This is not a US ANSI English QWERTY keycap set.

Durable PBT Material

Made from PBT plastic for a textured typing feel that helps resist shine, oiling, scratches, and everyday wear better than many standard ABS keycaps.

Dye-Sub Legends

Dye-sublimated legends are designed for long-lasting clarity through daily typing.

Cherry Profile Comfort

Cherry profile keycaps offer a comfortable lower-profile typing feel for work, study, gaming, and daily desk use.

Dark Underground Aesthetic

The dark colourway and accent legends create a sleek custom keyboard look for home offices, study setups, gaming desks, and aesthetic workstations.
