### ⭐⭐⭐⭐⭐ Perfect Notebook For Studies
*by L***A on January 24, 2026*

Arrived quickly, good condition over-all. Perfect for studying. The cover is plain but these are just research notebooks, you can bend the front flap comfortably and it is flexible. It's thicker and heavier than it looks but it has withstood some rough use already.
