INGENIOUS DOUBLE-WALL DESIGN

Ukiyo™ Sense 260ml bottle - 8.8oz - is made of high quality borosilicate glass. The double-wall glass is designed to let you enjoy hot or chilled beverages (check out the safety instructions here).

It will insulate the heat without burning your fingertips. Or you can just play it cool with a fruit or herbal chilled brew. 
The filter is made out of stainless steel mesh, resistant to odours, stains and bacteria. The central section is made of food-grade silicone and plastics, designed to withstand heat and humidity.
