4 Glass Tumblers

Our everyday glass tumbler is thin, strong and light – perfect for a refreshing glass of fizzy water, an iced coffee or a summer cocktail. Made in Japan by Toyo Sasaki Glass, the lightweight and thin-walled glass has undergone a special process to ensure high durability and scratch resistance, making it much stronger than traditional glassware. Which means you can get rid of any breakage fears! Available in a set of 4 glasses.
  • Set of 4
  • Lead-free soda-lime glass
  • Highly durable and thin rim
  • Excellent scratch-resistance
  • Crafted in Japan
  • Diameter: 80mm / 3.15''
  • H: 80mm / 3.15''
  • Capacity: 0.35l / 11.8''
  • Rim Thickness: 11.1mm / 0.44''

Perfect for everyday use, the glass tumblers can be washed in the dishwasher. A specially developed ion-toughening technique makes the glasses 1.6 times stronger than non-toughened glassware. If the glass starts to look cloudy over time, the most common cause is hard water. Simply soak the glass for 10 minutes in white vinegar to revive its shine.

The making of the Core Collection

Out of the fire

Our ceramics are made by a family-run factory in Portugal. They source clay locally and craft the pieces into our designed shapes. Before the pieces are completed, they are dipped in our unique glazes and single-fired, a process which minimises emissions.

Need Help? Just ask us.

Is your pottery food safe?

Yes, our manufacturer carries out thorough tests to ensure the clays and glazes are safe and 100% lead-free

Can I put it in the microwave or oven?

Yes, all our stoneware products are safe to use in the oven and microwave, to a temperature of 250 ºC. Steer clear of placing pieces straight from the oven on to a cold surface, as a measure against shock resistance.

How about the freezer?

Yes, absolutely. Our ceramics have high thermal shock resistance, and will withstand temperature variations as low as -20 ºC.

Is is dishwasher safe?

Yes, our products can be washed daily in the dishwasher. To ensure our dishes last longer it is advisable to space them so they don’t rub or bump against each other during the cycle. We recommend you wash the larger and more delicate pieces by hand, as a precaution.

Can I use it on the stove?

No. Monoware dinnerware is not suitable for stovetop cooking or for use with an open flame.
