15 oz Large Coffee Mug Set of 6, Wide Mouth Glass Mugs with Handle, Mocha Hot Beverage Mugs, Clear Espresso Cups for Hot or Cold Latte, Cappuccino, Tea, Juice, Beer

The mugs are thin while extremely strong and resistant to thermal shattering. Borosilicate glass is used in laboratory glassware and glass lenses due to its strength and low coefficient of thermal expansion. They are thin, strong, crystal clear, lightweight, stunning to look at and use and hold a full 15 ounces (440 ml) of liquid. This Amazon deal is incredible due to the price per unit combined with the high quality. I bought one set, used it for a month as a trial and then bought a second set. None have broken. We have taken them from the refrigerator to the microwave. They have become the favorite coffee mug for everyone in my family as well as visitors. I highly recommend them. A+

They are a lovely addition to my morning routine.1. Light weight2. Came out intact from dishwasher3. Boiled milk and water in it for 2 mins in microwave with no issues, handles are cold to touch while the contents are hot.4. I use it with my expresso machine, for instant coffee and tea.5. Minimalist and modern look6. They are delicate but strong for the intended use

I got these after throwing all my ceramic coffee mugs out when I read about the lead content ! So glad I found these - they are lightweight but durable and they are the perfect size for coffee and anything else, really high quality and look so cute in my kitchen!! And LEAD FREE ! Highly recommend! Especially for the price! Throw out or upcycle all your toxic ceramic!!

These mugs hold about 15 oz of liquid. The clarity is great and they' re surprisingly lightweight. They're all clean, clear and sparkly when I remove them from the dishwasher.

The mugs hold hot and cold liquids well. They are pretty in terms of transparency of the glass. They don’t do well in the dishwasher came out very spotty which means I have to hand wash them and my biggest concern is that they are really thin. I worry about breakage, nothing has broken but I’ve only use them a couple times. I’m not sure they’re suitable for daily wear.

Love these bigger mugs. Had to replace my original order in which the mugs basically lasted an average of a year - a year and a half at the longer: dropping, from hot to cold too fast, etc. You get the idea.... BUT I love these lighter bigger mugs because I drink a lot everyday: mostly yeas and an occasional spanish-style café manchado which I love. Just wishing they would last a lot longer!!

Compared to similar borosilicate glass mugs sold 10+ years ago the quality has improved and price is half of what was once charged. The mugs received did not have bubbles or rim defects, were sparkling clean and optically clear after weekly dishwasher cycles over a one year period. It shows off the color and clarity of fine teas very well.

Very thin, would break easily.
