Double-walled, heat-equalizing liquid holder, so that the setting of your acrylic does not speed up in the summer and does not slow down in the winter. It provides an optimal temperature for the correct setting speed. The brush can be completely dipped in the liquid without it touching the bottom of the jar. In this way, more liquid can be applied to the brush and the tip of the brush is not damaged. The cork stopper prevents the liquid from evaporating. In two colors.
