These are leftovers from a box of 5 that I opened 6 years ago. The bags have not been opened and have been stored in a dark place. Each one has a whitish area as shown in the third image. I wiped them with water, but it didn't come off. I haven't checked the contents, so I can't guarantee the quality. I'm hoping they're okay since they're unopened, but there's a chance they might not be usable, so please consider it a gamble.
