MacBook 12” Retina 2015 Intel Core M 1.3Ghz parts

Up for sale is a MacBook 12” Retina 2015 Edition! The laptop is in great physical condition but it boots up to a flashing folder! When I try to reset it using Apple Recovery method it takes me to a screen that says reinstall OS? But there is no SSD visible! I have no idea why it’s doing that! I am unable to install a operating system on this laptop! For this reason I am selling it for parts only! Please keep in mind this is a non working MacBook being sold for parts only!
