Apuntes is a notebook brand I am familiar with, but haven’t put to the test yet. I picked up several models from Amarillo Stationery recently, which is a new stationery shop focused on analog goods from Latin American. This Lineas Verticales model is a beautiful medium-sized hardcover notebook, checking in at 17.2 x 10.8 cm, which puts it just smaller than B6. It contains 200 pages (100 sheets) of 90 gsm ivory paper in a dot grid format.
I have one of these notebooks to give away this week, so read the rules and enter away!
