CASK Insulated Coffee Mug with Handle

The TYESO CASK insulated coffee mug brings a grounded, warm touch to everyday coffee and tea. A wood-look composite base balances its clean stainless steel form, while the open handle gives you a comfortable, familiar grip at home, at work, or between meetings.

Available in 18 oz and 24 oz, CASK suits both a morning coffee and a longer desk-side drink.

Why you'll reach for CASK

• Vacuum insulated: Double-wall insulation helps hot drinks stay warm and cold drinks stay refreshing for hours.
• Easy-sip lid: The clear sliding lid helps reduce everyday splashes and keeps the rim covered between sips.
• Food-grade stainless steel: The 18/8 stainless steel interior resists rust and lingering flavours.
• Comfortable handle: A balanced shape and easy grip suit desks, breakfast tables, and relaxed evenings.
• Two useful sizes: Choose 18 oz for a compact daily mug or 24 oz when you want more room.

• Do Not Microwave:
  This bottle is made of stainless steel and should never be placed in a microwave. Doing so may cause damage and pose a safety hazard.
• Store with Lid Off:
  After washing, allow the bottle to dry completely with the lid removed to prevent moisture buildup, mold, or odors.
• No Freezer:
  Do not place the bottle in the freezer. Liquids expand when frozen, which may damage the insulation or cause deformation.
• Avoid Direct Sunlight:
  Prolonged exposure to sunlight can fade colors and weaken the exterior coating. Store the bottle in a cool, dry place when not in use.
• Check for Wear Regularly:
  Inspect the lid, sealing gasket, and other parts from time to time. Replace worn components to maintain performance and leak resistance.
• Do Not Overfill:
  Leave some space at the top when filling with hot liquids to avoid spills and ensure a secure lid fit.
