OKO incorporates its 45 years of experience in the development of sealing fluids for extremely adverse operating conditions in the automotive, military and farming sectors into the development of Magic Milk for the bicycle industry. The result is the best tubeless sealant available on the market.

The sealing milk is very easy to use. You don't have to shake them or worry about sticking or stains. Since the tubeless milk is water-based and does not contain ammonia, it poses no danger to you or the environment. This composition also makes the sealant paint and tire friendly .

Due to its special and thicker consistency, the tire sealant adheres better to the inside of the tire than other thinner latex products and does not slosh around inside the tire. If necessary, the sealant in the tire can be refreshed or diluted with water. If you change your tire, you can simply wash the sealant out with water.

In contrast to OKO Magic Milk, Hi Fiber sealant contains more and larger fibers, which make it possible to seal larger cuts or damage to the tire.
