You've been signing delivery notes on a flimsy pad and the customer's copy comes out half-erased. Or the next page shows ghost writing from the one before. Stop. The Spirax 556 delivery book uses proper NCR paper so every copy lands clean. Spiral binding means it opens flat on a van seat or a workbench.

It's stocked and it ships when your order does
