Love Mintra’s Engineering Notebook - it has double ringed spine, 3-hole punched perforated pages, 5x5 boxes/1x1in, the sheets are a nice off-white and soo soo smooth 😍 Gel pens don’t bleed to other side nor do the highlighters - which is great since I hold my writing utensils very firmly. I haven’t tried with any fine liners yet. I seriously love the way my gel pens slide over the paper - I offered a sheet to a Mom the other day and she was super impressed with the quality of the paper too! Personally, I’ve been looking for a great grid paper notebook to make into my bullet journal (I’m a bit particular in my notebook selections) since I like enough space to have many trackers (year, month, week and weekly with time-grid) along with budget tracking and work schedules. I am so glad I stumbled across this notebook. It fits EVERYTHING and I have room to journal and sketch 🥰
I will say, my two suggestion would be:
1- adjust the paper composition so that Sharpie fine points don’t bleed through - that is a bit disappointing.
2- add a folder pocket page to the front or back.
Oh and lastly, it would be super amazing if the backside of the page were to be 4x4boxes/1x1in just to offer some flexibility. I know 5Star had one notebook offering like this, but it sold out faster than I was able to purchase… just a thought
