The Leitz plastic index Wow with numbers has an A4 oversized format and Euro hole punching. It can also be labeled via PC. The index is reusable and extra durable, made from PP in a vibrant color combination. A special feature: a standard A4 sheet can be labeled via the website and placed behind the transparent front cover of the index. This A4 sheet can be replaced as often as needed, allowing the index to be continuously updated. The indexes are printed in bright colors with numbers for clear sorting and quick access to documents.
