Does anyone know if the cases for the Onyx Boox fit? I would like to find something that's a bit more robust than what I'm using.

At this time, I'm using a case from Amazon. It's...cheap. Really cheap. The faux leather was flaking off before I even took it out of the wrapper. I like the "book" look of it, but I know it's not going to last. However, the straps hold it securely and it does add a modicum of drop protection. There's no pen holder, but I just slide the cap through the top holder on the side and it seems to work just fine. https://www.amazon.com/dp/B007W5B55A?psc=1&ref=ppx_yo2ov_dt_b_product_details
