All of our vases are made of borosilicate glass, a strong and durable material. The glass can withstand great temperature changes, and with regular cleaning, your vase will keep its shine and color for a long time. Even though borosilicate glass is a stronger material than regular glass, it is still glass and can not withstand impact. The FLOWER TUBE vase has a thin upper edge and can therefore be fragile. Be extra careful when unpacking this type of vase.View all glass vases here
