There are numerous colors of keys. You see white keys, black keys, red keys, orange keys, yellow keys, green keys, blue keys, violet keys, brown keys, pink keys, grey keys, turquoise keys, magenta keys, taupe keys, beige keys, aqua keys, navy keys, and cyan keys.
The colors are painted on the bows (the fat ends) of the keys; the metal shafts of the keys are bare. Every key is painted with exactly one color. There are no unpainted keys.

There's a handful of different brand names printed on the keys: Acme, Borden, Carter, Dynamo, Emperor, and Guardian.
> x sizes (@ Vault Antechamber)
There's just a few different distinct key sizes: tiny, small, big, and huge.
> x scratchness (@ Vault Antechamber)
Each key is either scratched or unscratched. Strangely, the scratches themselves are all just one tiny horizontal scratch, all alike and indistinguishable from each other.
> x shapes (@ Vault Antechamber)
The bows of keys come in several different shapes. They may be oval, circular, square, trapezoidal, hexagonal, or octagonal.
> x edgings (@ Vault Antechamber)
Carefully inspecting the keys before you, you notice that the edges of the keys' bows have different edging styles. Some edges are milled with tiny grooves. Some keys have pebbled edges which feel bumpy. Some keys have rounded edges. And, of course, some key edges are flat and unadorned.
