TOMLFF Penguin Stainless Steel Insulated Tumbler

This is a surprisingly small bottle—it holds approximately 9 ounces, which is less than a standard mug. Many buyers were caught off guard by the size, so think of it more as a personal portion or sampling size rather than an all-day beverage container. It's genuinely adorable, but if you're looking for something to keep you caffeinated through a long commute, you'll want a larger option.

It maintains temperature reasonably well for a few hours, but don't expect the same marathon performance as premium brands like Yeti or Hydro Flask. Several users noticed their drinks cooling throughout the day. For a quick tea break or a short outing, it works great—just don't rely on it to keep your gongfu tea piping hot from morning to afternoon.

People absolutely adore this thing. The penguin design gets mentioned more than almost any other feature—buyers call it 'cute,' 'adorable,' and note it makes a great gift. It's not just novelty either; the design is well-executed and durable. Just be aware that some users reported minor color bleeding where the black body meets the yellow beak and feet after extended use.

Most users report it's surprisingly tough—several mentioned it withstood drops without damage, which is impressive for something so cute and compact. However, there was one report of it breaking after a single drop, so it's not indestructible. The stainless steel construction is solid, but like any vacuum bottle, a hard impact in the wrong spot could compromise the seal.

Yes, and that's one of its best features. The compact, penguin-shaped design fits easily in car cup holders and slips into bags without taking up much space. Tea enthusiasts particularly appreciate this for carrying small portions of gongfu tea or sampling new blends on the go. It's genuinely portable in a way larger tumblers aren't.

Cleaning is straightforward—it's basically a screw-top bottle without complicated lids or straws. Users mention it's easy to hand wash, and several confirmed it's dishwasher safe. The simple design means no tricky crevices where tea stains can hide, which is always a win for daily tea drinkers.
