Bought my first sealed product last week, which I received today. Everything looks good on first sight, but then I noticed that every pack (out of 5) has a black strip inside the pack, which got me a bit worried. Can anyone confirm if this is legit, or could these packs be possible resealed? I added some pics below. Any help is greatly appreciated
Only first picture is visible somehow, added link
You are golden! Don’t worry
For resealed look for residues of glue
Looks good to me.
Great, thanks for the help! 
looks good are you gonna open them?
very likely legit, but only one way to know for sure. OPeN iT uP
Have to admit that it is tempting to open them haha. Keeping them sealed for now, though
