Maison Balzac Pomponette Gobelets

100% borosilicate glass. Although all Maison Balzac glassware is dishwasher safe, we recommend gently hand washing with a soft bristle brush as these are precious glasses. Avoid using strong alkali soaps, as these may damage the glass. Take care not to bump glassware against hard surfaces or other vessels during cleaning. Avoid putting ice directly in the empty glass; add the liquid first, then add ice and drink up.
