Magnesium for climbers, gymnasts, pole dance, fitness and other sports

At the beginning, there was the production of magnesium in the form of crushed chalk, gradually followed by the production of cubes, balls and ballocks. In the next stage, we developed our own formula for liquid magnesium suspension. Our research into new technologies and new product development following the needs and requirements of our customers still continues. Currently, we also offer liquid magnesium without rosin and with the addition of essential oils and fragrances. In addition to the traditional crushed magnesium, we also offer extra fine powder and dust. The properties and composition of crushed chalk, powder and dust can be adapted to the needs of our customers.

We produce magnesium products for the world's leading mountaineering companies. We have had close cooperation with the Swiss company Mammut since the beginning of our commercial activities.

In addition, we offer a complete range of magnesium for climbers under our own Chalk brand. We also produce magnesium for shooting sports, gymnastics, pole dancing and fitness.
