Review: Goduria - E davvero bello vedere i bambini quanta passione dedicano a questo attrezzo. La sua collocazione non può avvenire in casa in quanto un po' di rumore lo fa e andando di continuo anche per 7 GG di continuo non è il massimo. Lo consiglio a tutti i giovani esploratori che vogliono trasformare il grezzo in gioielli. Review: Great family activity. - The supplied rocks tumble really well, we also have tried our own rock finds and get satisfying results. Great for my autistic daughter who loves geology.
