The Union Plus Protective Index Label (405/Blue) is a functional label that prevents contamination and damage by applying a transparent protective film after writing names or content. With a blue border design, it offers good visibility and is great for identifying and classifying office supplies or personal items. It is based on the 405 model and is designed with a film-attachment structure to increase the preservation of the content. It supports neat labeling in various environments such as daily office settings or organizing school supplies.
