Please refrain from purchasing if you are overly concerned about details. As this is a hygiene product, returns are not accepted, so please review the images and description carefully before purchasing. I will no longer accept price reduction requests, as you don't seem to buy even after a price reduction. I will not reduce the price after a request is made.
