Modubooq Essential A5 - Modular Sustainable Smart Notebook A5-32 modular pages with duratech3 technology - Washable and writes like paper

I love the idea of wipe clean /reusable notebook. I have been using a similar in A5 but wanted one that fit in my pocket. I’m very disappointed that I can’t use my erasable pens in the book. The pen that came with the book smudges easily and the pages don’t come clean.
