Who invented disposable warmers? Although there are patent citations on this product dating all the way back to 1924, the Japanese introduced disposable warmers as we know them in 1978. In ten short years the market grew to over 450 million warmers per year. Although warmers have been imported to the States since 1980, it is only in recent years that the product has been widely distributed. Why are there so many suppliers of warmers? Due to the size of the Japanese market there are many manufacturers of this product that compete for a piece of the pie. However there are less than four manufacturers that together account for almost 90% of the market. The U.S. market is supplied by numerous importers who source their products from some of the many manufacturers in Japan. GRABBER imports warmers from the leader in the industry, MYCOALŽ. GRABBER and MYCOAL have an exclusive agreement in North America that allows GRABBER to offer the highest quality warmers on the market. As other companies may use more than one manufacturer, GRABBER uses only MYCOAL to ensure consistent quality with every warmerely distributed.
