Carry the tumbler upright and do not place it loose inside a bag. Frequently asked questions Can it hold hot drinks? Borosilicate glass tolerates temperature better than ordinary glass, but sudden thermal shock must still be avoided. Is the lid leakproof? No. Because the lid supports straw and sip openings, the tumbler should remain upright. Brand: Spring by LA' FORTE thoughtfully designed kitchen, storage, serveware and drinkware essentials.
