【Insulation Cup Usage Instructions】:

Before use, please first clean the cup with a neutral detergent.

Before use, please add hot or cold water to pre-cool or preheat, then pour it out and add again.

Pour hot or cold water.

Tighten the switch and lid in a clockwise direction to prevent leakage.

【Cups and Mugs Care】:

★ Add boiling water to the cup, but do not fill it to the brim. If you add too much water, it may overflow when you screw on the lid, which poses a risk of scalding.

★ Keep out of reach of children to prevent scalding.

★ When adding boiling water, avoid scalding, as the insulating effect ensures that the exterior of the cup will not become hot when hot beverages are added.

Avoid spills, falls, collisions, and strong impacts to prevent cup deformation and reduced insulation effectiveness.

★ Do not add the following substances to the vacuum insulated cup:

Dry ice, carbonated beverages, etc. (Internal pressure increase can lead to cup lids not opening or liquid spewing from the cup).

② Soy sauce, broth, and other salty or corrosive substances.

③ Avoid any form of direct heating.

★ Clean without using alkaline bleach, metal agents, or chemical cloths.

★ Do not place near fire sources such as fireplaces, as this may cause deformation and discoloration of the resin parts, reducing the insulation effect.
