I spent £25 on a Papier planner but the paper is COMPLETELY see-through, you can literally read everything on the opposite side of the page you are looking at and the writing on each page is obscured by that on the other side. I have uploaded photos, bear in mind this is just the writing printed into the planners, imagine how visible pen would be! I contacted them, providing photos, and they said that they recognised why I would be disappointed and that I could return the product but this would be at my own cost, even though the product is very clearly of an unsatisfactory quality and unfit for purpose (they are legally obligated to provide free returns in such instances). I have since read other reviews on their site and within 2 minutes came across 6 other people who had the same experience, many describing it the paper they use in their planners as 'tracing paper'. I purchased from them around a year ago and had no issues so they have clearly started using much thinner paper since then. Complete scammers, avoid!
