The waterproof pages can be cleaned and re-used, but you can also remove the notebook insert and replace it with our DT-WR5-Refill insert if you’d prefer to keep your notes intact.   The rugged, 2250D PU coated, woven ballistic nylon cover has clear pockets on the inside and outside of the back to hold dive tables, checklists, compass or other small items. The front cover includes elastic pencil holder compartments. A graphite pencil with leash is included, and is replaceable.   Wraparound bungee cord keeps the notebook securely closed when not in use.   Dimensions: Open (H × W): 20 cm × 25 cm (8" × 10") Closed (H × W): 20 cm × 12.5 cm (8" × 5")
