These lines suddenly appeared. Is this an easy fix? What should I do?

I had an old Norelco Bodygroom series that stopped working. I contacted Philips on this issue and was given a replacement for free. The issue is when I received it and opened it up, the original box it came in with looks like it has been opened. It did not look new.

I then mentioned this to them and returned it back for a new one. When I got the new bodygroom and opened the box, it did not come in the original retail packaging box but came in a brown box that had a sticker on it that taped it. When I opened it, the items seemed fine. My concern is if this item was refurbished or not due to the packaging. I read online that some replacements that come from the manufacturer might be in a brown box as opposed to retail packaging. I did read some items are refurbished and then repackaged into this.

What I do remember was a long time ago I bought a Norelco bodygroom from Amazon and it was at a discount and then the packaging came in a brown box just like this. I read that certain packaging is like this. The model is Norelco Bodygroom 7490/50. Anyone bought this model and received it in a brown box? What about those of you who had a warranty and then got a replacement. Did any Norelco Bodygroom you receive came in a brown box? I did read that some packaging is like this due to eco friendly.
