Plenty of room to keep information. This is much more sturdy than paper notebooks.Haven’t used them yet but I’m impressed with them at first glance. I write down notes at work I work as an electrician and I’ve been through many notepads Based on passed experiences with lower quality notepads I can tell by touching these that they will last and the paper feels thick.This is a well made booklet, i like it because it doesn't have a spiral and opens flat which being a lefty is very comfortable. Since I'm chef i have to keep notes on me so it stays closed and has a bookmark so i can quickly get to where i need to write it reviewI really like this little notebook. It's well made and very sturdy. The only problem so far is that the pen holder came unattached. I'm still giving five stars though, because I'm not sure if it was my fault or not by pulling the pen out of it too hard. So I'm not going to take a star away from it when it could possibly be my fault, so this is your warning to be careful when pulling the pen out of the holder. I should have held onto the pen holder with one hand, while pulling the pen out with the other. With all of that being said, I just need to glue it back in, and I'll be back to loving it again! ;)These have been in my apron since I bought them and holds up perfectly.Overall good product for the price, much cheaper than most. The only down side is the pen holder tends to come loose or come off after very few uses. I usually just pull them out when this happens and use the cover to hold my pen.This product is worth itSize. Easy fit into a pocket like a think wallet or small smart phone. The pages in the back are perferated for ease to tear out a list.El bloc cabe perfectamente en el bolsillo, es muy practica.
