I received amazing customer service, unfortunately due to the limited paper options I couldn't order in the end.
Strengths
It would be great if there were more paper options. I couldn't order my booklet because the white paper only comes in 80gsm and 250gsm. If there was a 180gsm I would have loved to order this and many future projects from you. A square booklet option would also be amazing.
Improvements or suggestions
I don't remember which keywords I used but I did find you with Google. So what you're doing works.
