Whether bombarded with UV rays in the desert or in freezing cold at the North Pole, the OTR.172 guarantees long lasting inscriptions on any surface like no other marker on the market.
The marker is made from well-proven OTR quality components made in Germany, like the solid refillable ink container and finely adjustable valve. Together with the durable felt tip made in Japan, the ink flow can be precisely controlled.
