How to use

Type or assemble the desired text, date or code to fit the 47 x 18 mm imprint area and install the rubber die according to the manufacturer’s instructions. Hold the stamp perpendicular to the target surface and press down evenly to transfer the impression. For best results, use moderate, steady pressure and ensure the target surface is flat and clean. Replace or re-ink the pad when impressions start to fade.

Usage recommendations

Store the stamp in a cool, dry place with the cap or housing closed to prevent ink from drying. Use original or compatible replacement pads designed for this model to maintain consistent ink coverage. When changing the pad, follow safe handling practices to avoid ink contact; if impressions become uneven, check that the rubber die is correctly seated and that the stamping surface is level.
