Round stamp 25 mm Centrum model 86921, self-inking office stamp

Centrum round self-inking stamp model 86921 provides a 25 mm diameter circular impression designed for routine office and administrative tasks. The compact unit is intended to produce consistent, repeatable stamps on paper documents, forms and lightweight packaging. It is reusable and built for multiple clear imprints before maintenance or re-inking is necessary, making it suitable for everyday stamping in businesses, schools and public institutions.

Advantages

The self-inking mechanism integrates the stamp plate and ink pad into a single compact housing, enabling quick single-step stamping without separate ink pads. A 25 mm impression diameter offers a balance between visibility and compactness for standard circular markings. The design supports consistent alignment and clear impressions across repeated uses, and the unit's reusable nature reduces the need for replacement parts during normal operation.

How to use

Place the stamp squarely over the target area on the document, press down evenly until the mechanism completes the imprint stroke, and then lift straight up to avoid smudging. For best results, ensure the surface is flat and free of debris. If impressions begin to fade after many uses, follow the manufacturer's re-inking or maintenance instructions appropriate for self-inking stamps to restore consistent print quality.

Usage recommendations

Store the stamp on a flat surface with the impression facing downward or upright in a dry environment to prolong ink pad life. Use paper and label surfaces compatible with standard water-based stamp inks to achieve optimal clarity.
