Rivers Drinkware Wallmug Bearl Solid, Double Walled Reusable Coffee Cup, 400ml, Black

I especially like those that have the aesthetic of an ordinary paper cup. I have been using this cup every day, bringing hot coffee to work and sometimes a nice iced coffee on the hot days, to keep me going throughout the day. The rivers cup does well not to leak however, the cup seems to lack heat retention for a lengthy duration. I found that I’d get 1-1.5 hrs of heat retention even with the double walls. That being said, it has been ok because it doesn’t hold a lot of liquid, despite the large size as the inner cup is quite narrow. I also bought the 350ml version which doesn't have double walls and is smaller but holds roughly the same amount of liquid. The design is great and when combined with a heat grip (for aesthetics) the overall look and feel is perfect for me. I like the fact you can pop this cup in the dishwasher for hassle-free cleaning. Overall I’m happy with this one for now but will look for a thermal cup with a similar design. For more reviews and unboxings follow my YouTube and Instagram of the same name.

振ったり倒したりすると漏れますが、縦のままかばんに入れて縦のまま持ち帰れば大丈夫でした。 保温性はそんなに無いですが、電子レンジが使えて便利です。

電子レンジOKで保温できるので買ってみましたが結構ぬるくなります、今は使ってません

見た目も良く電子レンジで使えるので便利です。 横に倒れた程度では溢れないと思いますが、蓋が開きやすいのとパッキンが丈夫ではないので鞄の中に横向きに入れるなどすると溢れるでしょう。 蓋の裏が入り組んでいるので少し洗いにくいです。

全く使い物にならない。

保温性は無くても軽い物をさがしていました。レンジが使えて便利だし、毎日使用してますが蓋がしっかり閉まるのでこぼれた事はありません。デザインもシンプルでとーってもお気に入りです。
