[4-Pack] Double-Wall Insulated Glass Coffee Mugs/Tea Cups, 12 Ounces, Double Walled Glasses Thermo Espresso

Delicate looks. Perfect performance. Over priced.

Insulated glass coffee mugs are also ideal as faux candle holders.

I bought these because they appeared to be solid replacements for similar glasses I have owned that were made by a major manufacturer--my old coffee mugs had broken over the years (accidents happen) and I was down to one of one size, and two of another; it was a mismatched 'collection' in need of an update. I was impressed by the quality when these glasses arrived; there was no large rubber plug in the bottom like you see in similar products made by other manufacturers, so these glasses sit flat; the glass is perfectly shaped; no defects, imperfections or areas that appear unusually thin, fragile or uneven. When I washed them before use one slipped from my wet fingers and bounced on its side, rolling around the sink until retrieved -- No chips/cracks or breaks. But please keep in mind these are brittle like any glass product; just because borosilicate glass handles temperature changes better than regular glass, these will break. Even though my 'close-call' shows me that these are durable, please don't be tempted to equate ruggedness with unbreakability. These glasses fit my hand perfectly--they feel solid without being heavy; they keep cold beverages cold/hot drinks hot. My first shipment arrived with one broken glass--a transit casualty; the company responded immediately and I had a replacement within a day -- Excellent product/excellent service -- Quality + Service + Great Price = Real Value -- I couldn't be happier!

The glasses work as advertised, remains very clear even after 1.5 years of use. I've bought more this time, and they arrived in excellent condition as well. Would recommend them.

Have been buying double wall glass cups for specialty hot coffees so I wanted these for all purpose cold beverages. Very impressed with the quality from this line as compared to other ones from different companies. They feel comfortable in the hand and are a full 12oz when filled to the brim so, 10 oz of liquid would be perfect in these. Must say milk not only looks delicious in these but also does stay colder & fresher longer. What I’ve learned is hand wash only & try not to saturate the bottom air hole with too much water while rinsing. Very happy with this purchase that was an Amazon’ choice. They also sit flat on the table without rocking around.

Los uso para servir bebidas calientes. Mantienen la temperatura aprox. 30 min (porque está abierto) y no se te pasa lo caliente.
