Do not twist the round rim against another vessel or use the chamfered corners to strike ice or hard objects. Wash and dry before first use. Inspect both walls, the rim junction, base, handle joins when present, and the small sealed maker vent mark before every use. Do not use glassware with a chip, crack, loose handle, open vent, trapped liquid between walls, or sharp edge. Avoid impact and sudden temperature changes; do not move directly between very hot and very cold conditions. Fill on a stable surface, leave headspace, and test beverage temperature carefully before drinking. Hand wash with mild detergent and a nonabrasive sponge, rinse, and dry fully. Do not insert tools between walls. No claim is made for microwave, oven, freezer, stovetop, or dishwasher compatibility.\u003c\/p\u003e","brand":"Zmkvn","offers":[{"title":"Default Title","offer_id":67641170755836,"sku":"ZMK-SQR-09-CL","price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0826\/1074\/9692\/files\/zmkvn-nine-ounce-square-outer-double-wall-borosilicate-tumbler-clear-main.jpg?v=1791015461","url":"https:\/\/zmkvn.us\/products\/zmkvn-nine-ounce-square-outer-double-wall-borosilicate-tumbler-clear","provider":"Zmkvn","version":"1.0","type":"link"}
