Thank you for viewing. This is an 8GB SONY Memory Stick PRO-HG Duo. I used it with my PSP, but I'm selling it because I won't be using it anymore. I have confirmed its operation and formatted it on a PC. It's in relatively good condition, but please understand that it is a used item before purchasing. I plan to ship it via Yu-Packet Post Mini, with the item wrapped in cushioning material. - Brand: SONY - Model Name: Memory Stick PRO-HG Duo - Capacity: 8GB - MAGICGATE: Yes
