Thermos JDG-350 S Vacuum Insulated Mug, 11.8 fl oz (350 ml), Stainless Steel

The 450ml one is actually smaller than Contigo 14oz mug. The lid is loose, you have to remove the lid to drink from the mug, but it’s easy to clean since it’s a solid piece of plastic with no drinking mechanism. Heat retention is pretty good for a loose-lid mug. Handle is round and comfortable to use.

This cup is a little smaller than the regular size cup but it’s good enough for me. I love that it comes with a lid.

Bought it from Amazon japan and received it three days after shipping. Great quality, almost 12oz ()Bought it from Amazon japan and received it three days after shipping. Great quality, almost 12oz (350ml）, can keep warm and cold, purchased at a discount, it's

Bought for my toddler and it's a good size and open cup for small hands.

Probably can only be used for baby or kid. The lid doesn’t close tightly, which makes it not as good as keeping the temperature

Sleek look, smaller than I thought, good quality

It’s a good product, but the lid is too loose.

Too small

As advertised

入院した時に蓋つきが欲しかったので、以前他で購入して、良かったのでこれは二個目です。冷たい水を入れておいても蓋はプラスチックでも、割と長い間冷たさを保ってくれます。

These mugs are only rated for above 67°C or below 8°C for 1 hour. But as typical with Japanese brands, they overpromise: 2-3 hours is easily achievable.It is light and look smaller than the amount it holds (350ml). Cold drinks do not form condensate around the mugs.Note: the lid just sits over the mug loosely and does not secure to form a seal.

Fast delivery in 6 days. Item received in good condition & only wish the cover is tighter.

Love it so much. It keeps the coffee hot throughout for more than one hour.
