The chalk pack I've bought is really uncomfortable to use. There are a lot of clumps that I need to break it each and every time before climbing. Its like I've poured water on my chalk bag by mistake.
It does works as a normal chalk for climbing
Too many clumps which I need break and use
Response of the brand
Hi Ashwin,
We thank you for your interest in our products and appreciate your feedback.
The magnesium chalk is a mix of pure powder and parts of fragments from the same material, a hybrid between a chalk block and powder. The chalk has the ability to get humidity and this phenomena is pronounced if it is powder. Also, climbers appreciate to break the few small blocks themselves. That's why, voluntarily we avoid to mill all the product to powder form. It also helps in less wastage. If the chalk you have is different than that, then maybe it it has absorbed more humidity and you can get it exchanged in the nearest Decathlon store.

I am available in case of any questions.
Happy Climbing!

Thanks and Regards,

Some chalk are too lumpy but generally ok... good to use for tug of war.
