Grivel Chalk Bag Trend Boulder is a boulder chalk holder with a modern and trendy style! Thanks to the flat bottom it is very stable and the very large opening allows you to dip both hands.To seal it in the best way, avoiding to spread magnesite around, there is a double closure, with lanyard and roll-top! It also has two practical handles that will allow you to safely transport from one boulder to another, both outdoors and indoors. Finally, there is a side pocket and two toothbrush holders.
