Ideal for professional millennials seeking a stylish, reusable travel mug that combines elegance with high-performance functionality. ## Description High Quality Hand Blown Borosilicate Glass Tumbler Borosilicate glass is well known for its durability and resistance to thermal shock This means it will not crack under extreme temperature changes like regular glass. It has the ability to go straight from a freezer to an oven rack without cracking. For you, this means you can pour boiling hot water into borosilicate glass Mug without worrying about shattering or cracking the glass. While Borosilicate is far more durable and resistant to thermal shock than other types of glass, it is glass so breakage is still a possibility. However, when broken, borosilicate glass tends to crack into larger pieces rather than shattering (it will snap rather than splinter), making clean up less hazardous than a typical glass. Borosilicate glass is hypoallergenic, lead-free and unlike a plastic straw, it is BPA-free. Have peace of mind knowing that no toxins are being leached into your beverages as you consume them! . Double Wall Construction for Hot and Cold Drinks Double layered glass mug insulates your drink keeping it hot or cold longer while the outside stays comfortable to your touch allowing you to embrace your drink while you sip at your drink's ideal temperature. High-quality FDA Food Grade Tested Silicone Silicone Seal to prevent any leaking while drinking Silicone sleeve to ensure a non-slip grip Silicone base on the bottom for glass protection Size 8 fl oz Worry FREE Purchase as we stand behind our products with our Unconditional Satisfaction Guarantee Click "Add to Cart" now to drink your perfect cup of coffee Review: Don't waste money - Poor quality Review: Beautiful, functional and my cat can't dip her paw in it! - I love purchases that I now I can live without! This very thoughtful and elegant design is well wrapped and secured with a silicone band in the mid-section and encapsulates the bottom. The mid-section stays cool to the touch with a very hot beverage inside the the double walled borosilicate glass walls. The weight and balance are perfect. Of course, I would suggest bouncing it off the walls or floor, it is sufficiently sturdy for my life. It hand washes very easily or washes perfectly on the top shelf of my dishwasher. Sipping out the slit on the top edge takes no learning curve and I can keep my eye on my phone or other screen when drinking. Best of all my office kitty is forced solely to drink from her bowl of water and not share from my glass or cup! I most highly recommend this splendid 8 oz cup. ## Features - GLASS SIP LID FOR NATURAL TASTE – All Glass Tumbler lid delivers a natural taste, without any plastic or metal aftertaste, and it is lead-free unlike plastic.
