Set of glass bowls named after the Lys River which traverses through France and Belgium. Lys Clear Stackable Bowls by Duralex are symbolic of what this wonderful tributary used to represent to some of France's most famed artists - clarity, simplicity, utility, and of course, beauty. These glass bowls are made with a collar on the rim making them stackable. Both impact and chip resistant, these bowls are extremely durable and ideal for everyday use. Tempered glass makes them equally suitable for hot and cold liquids. Dishwasher and microwave safe. Made in France.
