How to use

Insert the stack of documents into the cardboard sleeve and engage the metal clasp to secure the sheets.

Usage recommendations

For optimal performance, avoid overfilling beyond the capability of the clasp; distribute documents evenly and use multiple fasteners for thick sets. Store in a dry environment to preserve cardboard integrity and maintain the fastening mechanism.
