Product Description
Meet your new daily mug for home, office, and the outdoors. The RAYMYLO insulated coffee mug pairs a vacuum-sealed 304 stainless-steel body with a truly leak-proof slider lid, so you can pack it without worries. Drinks stay icy for up to 9 hours and comfortably hot for up to 3. The wide-mouth design lets you sip with or without a straw. If the lid feels snug (that’s how it stays leak-proof), confirm the silicone ring is seated flat and slide the tab while lifting to equalize pressure—off it comes.
