With the increasing global nature of business marketing and sourcing, Three-In-One has been able to take advantage of the special relationships we have with our customers in several foreign markets, particularly in Japan. The Japanese auto industry, like their US and other international counterparts has many specific tests requiring very specific test materials generally inaccessible to outside buyers because of small volume requirements and language problems. We have developed a very good working relationship with our Japanese associates. We are able to get many specified test materials required by Japanese auto test tool makers with assembly and manufacturing plants in Taiwan.
