Refund policy

1. 30-Day Satisfaction Guarantee

If your Mizzu tumbler develops a genuine issue within 30 days of delivery, we'll send a free replacement — free of charge, free of hassle.

What's covered

• Insulation failure (drinks not staying hot or cold as expected under normal use)
• Lid or seal leaking during normal use
• Powder coating peeling, bubbling, or chipping under normal use
• Manufacturing defects (dents, weld flaws, faulty threading) present out of the box or arising from normal use
• Rust or coating breakdown when the tumbler was used and cared for per our care instructions
  

What's not covered

So the guarantee stays fair (and free) for every Mizzu customer, it doesn't include:

• Damage from drops, impacts, or being run over, sat on, etc.
• Damage from the dishwasher, microwave, freezer, or stovetop, unless the product is labeled safe for that use
• Damage from carbonated beverages (carbonation can build pressure and cause lid failure)
• Normal cosmetic wear: minor scratches, scuffs, or fading from regular use
• Cosmetic preference or change of mind ("I don't like the color/size") — we don't offer returns or exchanges for this reason
• Items purchased secondhand, gifted without the original order number, or bought through unauthorized resellers
