LG G7 One (2018) battery back cover glass + fingerprint scanner and lens.
The backs have a matt finish and I'm pretty sure the colour is Aurora Black but it does have a bluey/grey hint to it under certain light.
Grade A..excellent condition, minimal blemishes.
These are genuine parts removed from LG handsets so may still have the old adhesive attached which will need removing and replacing with a new adhesive template (not included).
