This mid-2015 15-inch Retina MacBook Pro was purchased new in 2017.  It boots up and will function but the battery needs to be replaced and the CPU and GPU temperatures are high, and there is a small chip on the screen (see picture).  Because of these issues it is being sold "AS IS" for repair or parts.  There is an i7 processor with 16GB of RAM and a 1TB SSD (Flash Storage).  Original Apple charger included.  Stored in a smoke-free home
