  • Uncomfortable Handles

    The fixed size and shape of traditional mug handles can cause discomfort for different hand sizes.

  • Weight Imbalance

    Handles on one side of a mug can disrupt weight distribution, making it challenging to hold the mug steadily and comfortably.

  • Too Hot to Handle

    But handle-less mugs risk direct contact, leading to discomfort or safety concerns.

Pour. Grab. Sip.

Experience ONU’s innovative handleless mugs and redefine your daily coffee or tea ritual, one sip at a time.

  • Comfortable Grip

    With ONU, designed without handles but with double insulation, you can savor the warmth without the burn.

  • Maintain Temperature

    Thanks to ONU’s special secret, your beverage stays warmer for longer, allowing you to savor your daily ritual with extended satisfaction.

  • Handmade Porcelain

    The result of meticulous craftsmanship by our skilled ceramic artist, ONU is a unique and stylish mug, unlike any other in the world.

Hollow. That's Our Secret.

By crafting the inner and outer forms separately and seamlessly merging them into one, we’ve ingeniously created a hollow design within the mug’s wall.

Heat is cleverly channeled into the hollow space, preventing direct transfer to the outer wall. That’s why you can keep your hands warm, not burn.

Backed by science. Not just another design product.

Our temperature test revealed that the surface of ONU consistently remains warm, well within the comfortable temperature range for most people. 

In contrast, the normal porcelain cup showed a significantly higher temperature, which may cause a burn or injury.
