TOMLFF Penguin Stainless Steel Insulated Tumbler

Reviewers report it keeps hot drinks warm for several hours, which is enough for a morning commute or a short outing. However, don't expect it to keep your tea hot all day — a couple of reviewers note the heat doesn't last for extended periods. For a 9oz container, that's pretty typical. If you need all-day heat retention, a larger vacuum flask with a narrower mouth would be a better choice. For a cup of tea that stays warm through a meeting or a car ride, though, it does the job.

This is actually one of the best use cases for it. The small 9oz size is perfect for little hands, the screw-on cap has no complicated mechanisms for kids to struggle with, and it's durable enough to handle the occasional drop. Several reviewers specifically mention using it as a children's water bottle or hot beverage container. The adorable penguin design is a huge hit with kids too — 15 reviewers mention how cute it is. Just be careful with hot liquids for younger children since there's no locking mechanism on the cap.

This tumbler has a few sweet spots. It's ideal for kids who need a small, durable drink container with a fun design. It's great as a gift for anyone who loves penguins — 15 reviewers gush about the cute design. It works well for adults who want a compact single cup of tea or coffee for short commutes, and it's handy for bedside water storage or car cup holder use. Where it's not ideal: adults who need a full day's worth of hydration, anyone expecting a standard thermos size, or people who want all-day heat retention.

Yes — cleaning is straightforward. The wide neck lets you get a brush or sponge inside easily, and reviewers confirm it's simple to wash by hand. Some reviewers also mention it's dishwasher safe, which is a nice bonus. The simple screw-on cap doesn't have hidden crevices or gaskets that trap residue, so there aren't many spots for buildup or mold to develop.

Based on customer feedback, this penguin tumbler holds up well to everyday use — multiple reviewers mention it being durable and withstanding drops without issue. The stainless steel vacuum construction is built to last. That said, one reviewer did report theirs broke after a single drop, so results can vary. For most people using it daily, expect it to last a good while with normal care. One thing to watch for over time is potential color bleeding, where the black paint can bleed into the yellow beak and feet areas.

A couple of reviewers have reported color bleeding, specifically the black paint running into the yellow beak and feet areas of the penguin design. This seems to be an occasional quality control issue rather than something that happens to every unit. Hand washing may help preserve the design longer, even if the tumbler is technically dishwasher safe.

Absolutely. While the listing mentions tea, coffee, and water, reviewers confirm it works great for any hot or cold beverage. The stainless steel interior won't absorb flavors, and the wide neck makes it easy to pour coffee in. One reviewer even uses it to bring milk for cereal to work. Just keep in mind the ~9oz capacity means you're getting a small cup of coffee, not a venti-sized serving.

No — reviewers specifically mention that the screw-on cap is easy to use and doesn't jam. The simple twist-on mechanism means there are no buttons, latches, or sliding parts that could get stuck or break. It's one of the things that makes this tumbler particularly child-friendly.

The TOMLFF penguin tumbler is about as simple as it gets. Unscrew the cap, pour in your tea (or coffee, water, whatever you like), and screw it back on. There's no built-in infuser, so you'll want to brew your tea separately and pour it in, or use a small tea bag that you can drop right inside — the wide neck makes that easy. The ~9oz capacity is roughly one small cup, so it's perfect for a single serving of gongfu-style tea or a quick pick-me-up drink.

Just one regular-sized tea bag is perfect. The TOMLFF penguin tumbler holds approximately 9oz, which is basically a single cup of tea. One standard tea bag will give you a well-flavored cup at that volume. If you prefer stronger tea, you could use one bag and steep a bit longer rather than adding a second — there's really not enough water in there for two bags anyway.

Interestingly, yes — the small ~9oz capacity that some reviewers see as a drawback is actually a plus for gongfu-style tea drinking, where you're working with small, concentrated portions. The stainless steel vacuum insulation keeps your tea at a good temperature while you sip, and the compact size makes it perfect for carrying sample-sized portions. If you're into minimalist travel tea setups, this could work well as a receiving vessel for your gaiwan or small teapot.
