Why selected: The stamp supports up to 15,000 clear impressions before refilling and can reach up to 50,000 impressions before re-inking, reducing downtime on busy sites. Its durable design suits frequent handling and transport in field conditions.
Caution: While highly portable, the ink is oil-based; avoid use on surfaces where oil-based marks may be undesirable or difficult to remove. Ensure surfaces are compatible with black oil-based ink before stamping.
