TOMLFF Penguin Insulated Stainless Steel Tumbler

No — the screw-on cap gets consistent praise from reviewers for not leaking. Four reviewers specifically mention having zero leaking issues, and the simple screw mechanism means it doesn't jam either. It's a straightforward twist-on, twist-off design with no flip lids or push buttons to malfunction. This is one of the things buyers seem most happy with about the tumbler.

Surprisingly durable for its price point. Eight reviewers specifically mention it withstanding drops, and one memorable review notes it even survived being used as a dog chew toy — scratched up but still functional. The stainless steel construction holds up well to daily handling, which makes it especially practical for kids who aren't exactly gentle with their things. That said, one reviewer did report theirs broke after a single drop, so results can vary.

You can, but most reviewers find it too small for adult daily use. At around 9 ounces, it holds about one small cup of coffee or tea — not nearly enough for staying hydrated through a workday. That said, some reviewers found clever uses: keeping it at their bedside for water to take pills, or bringing a small portion of milk for cereal at work. If you're looking for a proper adult work tumbler, you'll want something larger. This one is best suited for kids, short trips, or as a novelty item.

Based on what reviewers actually use it for, the top uses are: a children's water bottle (ages 3-10), a bedside water bottle for taking pills at night, a car cup holder companion for short trips, and a novelty gift for penguin fans. Some people also use it as a small container for candy or snacks. It's one of those products that found its real audience despite being marketed as an adult travel mug — kids and penguin collectors love it the most.

The penguin design makes it a genuinely fun gift, especially for penguin lovers or kids. One creative reviewer even filled it with chocolates as gift packaging. However, be aware that the original packaging is poor quality with Chinese-only text, so it won't look premium straight out of the box. If you're gifting it, you'll probably want to remove the original packaging and present it in your own gift bag or wrapping. The tumbler itself looks great — it's just the box that lets it down.

It's about as simple as it gets — just unscrew the cap, pour in your tea, and screw the cap back on. Reviewers love that the screw-top design doesn't jam or leak. One tip: since it only holds around 9 ounces, brew a single cup's worth of tea. It keeps hot drinks warm for several hours, though it's not a true thermos, so don't expect piping hot tea 8 hours later. For cleaning, you can hand wash it or toss it in the dishwasher.

Yes — multiple reviewers confirm it fits easily in standard car cup holders. Its compact size is actually an advantage here. It also fits in coat pockets, which makes it genuinely portable. If you're looking for a small tumbler for short car trips or walks, the size works in its favor.

Cleaning is easy — you can either hand wash it or put it in the dishwasher. Reviewers mention both methods work well with no issues. The wide screw-top opening makes hand washing straightforward, and the stainless steel interior doesn't retain flavors the way plastic bottles can. No special care instructions needed.

A couple of reviewers noticed color bleeding, specifically the black paint transferring onto the yellow beak and feet of the penguin design. It's not a widespread complaint — only two mentions — but it's worth knowing about if the appearance matters a lot to you. The tumbler still functions perfectly fine, it's purely a cosmetic issue.

When choosing a travel tea tumbler, think about what matters most: size, insulation, and how you'll carry it. The TOMLFF Penguin is vacuum insulated stainless steel, which keeps drinks hot or cold for 3-6 hours according to reviewers. It's compact enough to fit in car cup holders and coat pockets, which is a big plus for on-the-go use. Just keep in mind it holds about 9 ounces — great for a single cup of tea, but not enough if you need all-day hydration.
