Use as the ultimate lab book or as an over-sized companion for diagrams and sketches. The 21.5cm x 28cm Field-Flex Maxi Book contains 128 pages (64 sheets). Each sheet is our heavier 32# Rite in the Rain waterproof, weather-proof paper.
The Rite in the Rain paper works, there's no doubt about that, so that's a good reason to buy this brand of notebook, next though is which format you need. The 373MX and the 374MX are both A4 format, which is an ideal size for larger project work or more involved writing. The choice is then between spiral bound, which allows the book to fold flat and is therefore easier for writing on, and a glue binding, which is more robust but can still be folded relatively flat.
The pages consist of blue horizontal lines with faint vertical lines forming a grid pattern should you want to use it. There's a contents page on the inside front cover.
