One Mug for Both Coffee and Tea
The Tea & Coffee Maker Mug is a mug with a strainer that lets you enjoy both coffee and tea in a single mug. The fine-mesh strainer can also brew coffee, and after brewing, the strainer can be hung on the rim of the mug to drain. The vacuum double-wall construction also makes it easy to keep drinks at a good drinking temperature.
Smooth Feel and Easy Care
The mug body has a ceramic coating, giving it a smooth, ceramic-like feel in the mouth even though it is made of stainless steel. It is less likely to interfere with the flavor of coffee or tea, and stains such as tea stains are easy to remove, making it easy to use every day.
Users of the mug have also given positive feedback on its feel in the mouth, ease of care, and heat retention.
Separate Lids for the Strainer Rest and for Drinking
After brewing, the removed strainer can be placed on the existing lid turned upside down. However, some users said that when the existing lid is used as a strainer rest, it cannot be used as a lid while drinking.
So the set now comes with a new sliding insulating lid that can be used while drinking.
The existing lid serves as the strainer rest, and the sliding insulating lid is used while drinking, so each lid can be used for its own purpose. Because the lid slides, you can enjoy your drink with the lid still on. This is convenient when you want to take your time over a hot coffee or tea.
Popular Greige, Now with an Insulating Lid
The set is made in the popular Greige color. The mug body and insulating lid come in the same color, with a calm tone that blends into daily coffee time and tea time.
Greige Plus keeps the ease of use of the Tea & Coffee Maker Mug and adds the insulating lid. It is a new set for enjoying your daily cup more comfortably on Coffee Day.
