Finally, a stylish and sustainable go-everywhere cup that’s perfect for drinks at the beach, picnics, camping, festivals, barbeques, poolside or on the water - with no breakable glass! Made with 304 grade premium stainless steel 354ml capacity Double-walled and vacuum insulated to keep beverages cold for 8 hours and hot for 4 hours Wide opening for ice cubes Sliding lid for easy drinking straight from the cup, or use with a stainless steel straw Note: This tumbler is not leakproof so should be transported in an upright position. Care Ever Eco Insulated Tumblers are made to last. Making sure you care for your tumbler correctly will mean it’ll be with you for many years to come! Hand wash only with a gentle brush or dishcloth. Do not put in the dishwasher- this can compromise the double wall insulation and external powder-coated finish. Avoid contact with sharp or abrasive objects. Avoid placing upside down in a metal dish rack, as over time this can cause the paint to chip around the rim. Dry straight away or place on a drying mat/tea towel.
