I originally bought mine with the keyboard folio case and decided to return the case - it made the Remarkable heavier and thicker than it needed to be and I didn’t like the size of the keyboard.
I was going to get one of the branded flap folio cases instead but thought I’d give this Amazon one a go first. £35 which is soooo much cheaper and I’m really happy with it! https://www.amazon.co.uk/dp/B094NBGG78?ref=ppx_pop_mob_ap_share
I understand as I have the original items because I’m an individual that like the specific branded items, however I’m a bargain shopper too. I got the Type Folio during the discount but I have every case and both type folio by purchasing/biding on either E-Bay, Mercari and Poshmark for fraction of the cost. Ive been able to get all my family members remarkable 2, just have to be savvy, set up your notifications and learn the systems, look at the pictures real good, read the descriptions. People have sold including me, the whole remarkable, type folio and marker plus for $375. Also, I agree there are other pen options that people say are really good. I have the Lamy but I enjoy writing with the marker plus. I think they all are pretty expensive even the Supernote accessories.
I bought a nice case off Amazon for 20€ and the Staedler Noris Jumbo pen with eraser for much less than the remarkable pro pen. So yeah.
