Objects of beauty

Chalk in a ball at a great price. Errrrr cant think of much more to say about a ball of chalk. Oh, they're great for throwing at the wife when she's shouldering bouldering and leave a great mark.

Great ball for the wall

Handy chalk for the climbing wall however does come out lightly so may need to give it a big pat!

it's not chalky

the most disappointing experience of my life, well as far as chalk is concerned. I was given one as a present, I normally use the block chalk which works fine

Hello Marc,

Thank you for reviewing the Simond Small Deposit Chalk Ball. I am sorry to hear that it did not meet you expectations. The Low Deffusion Chalk Ball is designed to only give out a small amount of chalk as it is aimed at beginner climbers; we do have a High Deffusion Chalk Ball (Link Below) thats allows for a lot more chalk to put onto you hands and is aimed at the more advanced climber. We do also sell the Block Chalk you mentioned in you review (Link Below)

Once again thank you for the feedback.

Para rítmica

Mi sobrina me la ha pedido porque ya es la tercera que gasta y está encantada

El magnesio marca Simon en todas sus presentaciones es muy malo no se addiere a la piel, el formato en bolas ,es intratable, solo sirve para marcar agarre, No sale el magnesio de la bola

Hola Javier.

Muchas gracias por tu comentario.

Este producto en concreto es de baja difusión, por lo que podrás notar que sale mucho menos magnesio que en la otra bola que disponemos de alta difusión.

De todas formas si no estas conforme con la compra del producto podrás cambiarlo por la otra bola si lo deseas en cualquiera de nuestras tiendas Decathlon, ya que dispones de 60 días de prueba del producto y si no te convence podrás tramitar dicho cambio.

Espero haberte ayudado.

Muchas gracias por tu confianza en la marca.

Un saludo.

Marcos, experto en deportes de verticalidad.

No me termina de convencer

Para mi no termina de convencerme, no quiere decir que sea malo ni bueno, solo que prefiero otro tipo de magnesio, como el líquido.

Muy útil para dosificar magnesio dentro de un recipiente de magnesio
