This is Glass! I got them from  Alber.v in a Fursona Trade! I love them so much!

Some info:
Pronouns: They/It/He/She in that order
Gender identity: Agender
Sexual orientation: Cupioromatic Asexual
Nickname for tail: Bitey (for obvious reasons)
Their arms are made of a glass-like substance that is strong enough to stay intact in rough situations. The "ribs" are also made of this substance.

Thanks again for trading with me  Alber.V
