Are stickers on products that cannot be removed or are difficult to remove a defect?
I have often had the problem that products I had ordered online had stickers on them that were very difficult to remove – in some cases, residues were even left on the product that could not be removed even with adhesive remover.
The last time it was a perforated board where the seller had stuck a fat and extremely adhesive sticker directly onto the board.
Do you consider this a product defect?
Only if the sticker impairs the functionality of the goods.
That is, if someone buys an oil painting from Pikasso and on the front of the picture next to the signature of the artist would be on the picture a strongly adhering sticker, then would that be OK?
Bad example In the case of paintings, the stickers are on the back and it is even recommended not to remove them because they reject the history owners of the painting, so these stickers are the identity of the painting.
Better example, you buy a pan and don't get the sticker in the middle, so you can't use the pan and here the dealer would have to actually repair, give you a new pan.
