Okay, so I've been using this A5 vegan leather cover for my Rocketbook for a few weeks now, and here's the real tea:
First off, the material feels SO nice - like way better than I expected for faux leather. It's soft but doesn't feel cheap at all. The mint green color I got is actually prettier in person than in the photos.
The pockets are super practical - I can fit my Rocketbook, a small notebook, pens, and even my phone in there. The card slots are perfect for my ID and credit cards when I'm running to coffee shops to work.
That said... it did have a slight weird smell when it first arrived? But it went away after like two days of airing out. Also if you have the full-size Rocketbook, double check measurements because this fits the smaller one perfectly but might be tight for larger notebooks.
Overall? 9/10 would recommend. It makes me feel fancy and organized without being bulky. Plus it looks professional enough for work meetings but cute enough that it doesn't feel boring.
