I just received some etmamu (etsy shop) A5 spiral bound notebooks. I got the dot grid version and they have great paper. Oh, and the spiral is fairly small so I don’t expect it to get in the way too much. And at less than 4€ per notebook you can’t really go wrong!
Which design did you get?
Looks nice! Hurts my eyes a little, but still nice 
my favorite would be the old door, I like those designs.
