Madu ClimbRefillable Chalk Ball – Crux Technology for Even Distribution – 100% Pure Micronised Magnesium Carbonate (MgCO₃) – No Fillers – Ideal for Climbing, Gym, Weightlifting & Bouldering

Bought for Christmas stocking filler so not completely opened yet but from what I can see is just as described and arrived quickly. Good price .

Does the job this, when it turns up it doesn't look the best but as long as it works I'm not bothered. This is easily refillable and it's a decent way to stop me getting chalk everywhere. ,

I got this because I wanted a refillable chalk ballbag, the bag is decent. The chalk is okay, nothing special but nothing wrong with it. Definitely worth the buy if you want a ballbag you can refill with some decent chalk.

My children are new to climbing and to be honest I misunderstood exactly what I was ordering but I'm really happy with it. This is a fine mesh ball that is designed for the chalk to leak out through the mesh, specifically when you squeeze it- so you squeeze with each hand and get a single dose on each, without a huge amount being spilt everywhere. This is such a great idea- my kids always over chalk their hands and get loads on the floor and this limits this. However because this is designed to 'leak' chalk it does mean you really want a second bag to store it in. We are using it inside a dog treat bag which has plenty of space for them to put thier hand in and squeeze the chalk ball whilst still in the bag. It has a drawstring so can be refilled whenever needed. Very happy. Great product

Elastic broke after a week's use, rending the chalk ball ineffective.

Nice and big! i use it for indoor climbing! Also refillable so no need to re buy
