Around my sophomore year I finally found green engineering pads. I believe they were TOPS brand. At $4-$5 a piece, they were definitely much more than my k-12 $0.10 on-sale spiral notebooks & stolen printer paper. I filled up dozens of them & love them to this day.
I also bought high(ish) quality laminated folders & further reinforced them with Gorilla tape. This also came after using fairly janky ones most of my life, & not being able to find anything that satisfied me once I went for something new. I still use many I made in 2017.
Got a fair amount of questions about them throughout school.
The Pentel Graphgear 1000’s are an amazing writing tool, as are their Hi-Polymer block erasers. I’ve found nothing able to come close to the Pentel block erasers, and I’m surprised that Staedtler’s have not been completely laughed off the market by this point.
