I bought this to see if it would encourage me to sketch, but apart from making sure it worked I’ve not really used it. It’s been attached to my iPad Air and that’s about it…..it just stays there! So, as I’m not using it and it’s not comparable with the 13” model iPad I’m looking at trading up to, it may as well go to someone who will make use of it. Last pic shows 2 tiny marks where the pencil magnets attach to the iPad. You may struggle to see them but they are there.
