Lot of 28 RAM sticks pulled from working MacBook Pro models. All modules were removed from fully functioning systems and worked properly at the time of disassembly. They have been handled carefully and are in good used condition. The exact specifications (capacity, speed, and other details) are clearly listed on each individual stick, so please refer to the labels in the photos for full details. If you have any questions or need a closer look at anything, feel free to let me know!
