Helps Poshing
It helps shaping stones too..it is a little sound and I'm living 2floor so I put a box on it to make the noise more silent

Muy satisfecha
El proceso de pulir piedras es algo largo, pero el producto hace su labor. Viene suficiente cantidad para varias tandas y es muy sencillo de usar, ya que cada paso esta numerado.

Très bien
C'est un petit investissement, j'aurai aimé pouvoir acheter pot par pot car je n'utilise que le n°1 et n°3, mais ça reste très efficace, bon rapport quantité/qualité/prix. Et une seule cuillère c'est dommage car il reste toujours un peu de poudre quand on la vide donc on contamine un petit peu les autres pots... Mais ce n'est qu'un détail.
