O/S Aluminum Clipboard | Highly Durable Aluminum Clipboard PENCO's standard clipboard is now available in aluminum plate specifications. This item boasts a lightweight yet sturdy construction. It can be used for heavy-duty purposes with the longest durability in the O/S clipboard series. There's a scale on the side, making it easy to use, such as using it as a small measurement in the middle of work. The clip is also sturdy and powerful, so you won't lose the documents you place on it. Please use it not only for office use but also for various scenarios. It is available in A4 and A5 sizes, which are easy to use in the office. The clip part is the same as a regular O/S clipboard. Because it has strong clamping force, it is ideal not only for documents but also for legal strokes. On the right side, there are scales at 1mm intervals (1cm interval for numerical display). It is not printed, but it is an irregular specification that does not easily fade even after long-term use.
