This is a hand-made and resin-casted artisan keycap in the “Mortem” sculpt style, made by encapsulating a Mortem in a regular SA R1 blank. This particular colorway features a white skull on a sparkly Tiffany blue base. This cap is one of the very few made that is the first version of the Mortem internal sculpt, before the crossbones were added. The outer blank is also slightly yellowed from UV exposure, hence the discount. MX-compatible stem.
