Paperdry Weather Clipboard - A4 Landscape A spring-loaded cover protects your papers from the rain and wind while you write, and it closes with strong velcro to keep them secure and dry when not in use. Since it's see-through, you can refer to your documents at any time. A clip inside the cover keeps your papers secure. On A4 models, there's a clip on the back of the clipboard (and two clips on the A3 model). On the A4 and A3 models, there are two small slots inside the clipboard to hold your pen and pencil. There are several different grades of PVC available. Here at Paperdry, we only use the best: it's thicker and also treated with a cold-proofing agent, meaning our clipboards don't crack in cold weather. They're robust and durable, and an 18 month warranty is included as standard.
