The battery is clean, has never been opened or used before. The types of batteries are written, and the Huawei battery fits Huawei Y6 and Y5. The Samsung battery is sold for 70 or more. I want 50 for each battery, and if you want them all, I won't shortchange you. And for the cases, I usually take 10 for them, as they are 15 in the stores, and even 20 depending on the store and the type of case. The transparent ones don't turn yellow.
