Thank you for viewing. This is a set of 5 I7 wafer cards. After purchase, they were stored personally at home. I do not smoke, and I do not have any pets. There is no problem with reading them, but they were manufactured about 30 years ago, so please be sure to check the photos and purchase them with no returns and no claims. This is a used item, so please refrain from purchasing if you are nervous about it. Due to work, I may be late in responding. I will try to ship as soon as possible, but it may take 2-3 days from the money transfer procedure, so please understand. Thank you.
