MILLY BARWARE When ordering you may assort the colors if you prefer. Mario Luca Giusti acrylic is a great substitute for glass. Acrylic will not yellow and the colors are weather and sunlight resistant. MLG products are BPA free. Hand wash all acrylics with warm water to maintain optimal appearance. Although it resists most chemicals found in normal use, dishwasher rinse agents can cause cracking and crazing (hairline cracks) on the surface. NOT recommended for use in the dishwasher or microwave.
