Tyeso Bottles Are Lead Free. Always Have Been. Always Will
Be.

In light of recent media attention on the subject, we affirm our commitment to consumer safety by highlighting the fact that all Tyeso bottles and tumblers are and always have been lead free.

True to our ethos of challenging the industry standard, we utilized an innovative, lead-free solder in our products from the very beginning-just one example of our commitment to prioritize consumer safety and well-being above all else.

Stainless Steel

The lids are top-rack dishwasher safe, and the straws can go in the silverware
bin. The cups are also technically dishwasher safe as well, but we strongly
recommend you hand-wash them to maintain that beautiful finish.

Plastic

All parts are top-rack dishwasher safe.

Stainless Steel

The stainless-steel bottles should never be microwaved.

Plastic

For plastic, microwaving is strongly discouraged. Like, very strongly discouraged. The leak-proof seal can allow
pressure to build up inside the bottle when heating, causing the lid or flip
cap to open unexpectedly and spray contents.

So…just don’t go there.

Stainless Steel: We’re assuming that if you want to freeze your bottle, it’s because you want your liquids to be cold. But here’s the thing: our stainless-steel bottles are triple-layer insulated, which means that the liquids are insulated from the temperature outside of the bottle. So while yes, the bottle is technically freezer safe, we just recommend putting a few ice cubes in the bottle instead.

• Wash before use. Lid is top-rack dishwasher safe. Hand washing the cup is recommended to preserve its finish. Do not use harsh chemicals (such as bleach, abrasives, etc.).
• Do not microwave, freeze, or boil.
• Not for use with hot, carbonated, or perishable liquids.

Warnings

• Drinking hot liquids presents a risk of injury.
• The straw allows generous amounts of liquid to be drawn suddenly into the mouth from the bottom of the bottle where the temperature of hot liquids is usually higher than it is at the liquid's surface.
• Hot, carbonated, and perishable liquids and other contents may build up pressure within the bottle and unexpectedly leak or spray out. Pressurized contents also may cause the spout cover to open rapidly enough to injure fingers positioned in or near the recess behind the spout cover. Always open with caution.
• Please don’t shake when there is hot water in bottle, it may be very dangerous. When open the lid, please open it slowly and carefully because there might be heat coming out of the bottle.

Everyday is good but it’s up to you.
