Product description

Compact, travel‑friendly dimensions: This slim 5oz (150ml) insulated flask measures roughly 5.6 inches high by 2.2 inches wide, designed to slide into small handbags, coat pockets, purse compartments, cup holders and tight carry spaces. Its petite footprint makes it convenient when you only want a small serving of water, coffee, or a supplement‑taking sip.

Materials and construction: The bottle is constructed from 18/8 (304) food‑grade stainless steel for corrosion resistance and minimal flavor transfer. The interior is smooth stainless for easy rinsing and to avoid lingering odors. The screw‑top lid includes an integrated silicone sealing ring to create a tight, leak‑resistant closure.

Insulation and temperature claims: Double‑wall vacuum insulation is used to slow heat transfer; the manufacturer’s guidance places short‑term hot and cold retention in the several‑hour range. Because of its small volume, it cools or warms more quickly than larger thermoses, but it still helps keep drinks at a more stable temperature for a useful window of time.

What’s included and how to use: The package contains the 5oz insulated bottle and its matching screw cap with silicone gasket. Fill it, close the lid until snug, and carry it upright or horizontally in a bag without worrying about typical drips. The wide opening accepts ice cubes and allows easy access for cleaning with a bottle brush. Use it as a backup water supply, an espresso or coffee carrier, a compact tea flask, or a small travel beverage container for short trips.

Pros

Truly pocketable 5oz size fits small bags and cup holders
Food‑grade 18/8 stainless interior resists rust and odors

VerdictA cleverly compact insulated bottle for anyone who wants a lightweight, durable miniature flask for quick sips on the go. It’s built from 18/8 stainless steel, uses double‑wall vacuum insulation and a silicone‑sealed screw lid to prevent spills. While its 5oz capacity means frequent refills, the slim size makes it perfect as a purse backup, travel companion, or tiny coffee flask. Expect good durab

Reviews

Linda S 5/5

Cute, versatile, and leakproof

It’s absolutely adorable and very useful. I planned to use it as a tiny everyday water bottle, especially in warm weather, and I was relieved to find it doesn’t leak. It also holds a single cup of espresso perfectly. The wide mouth makes pouring and filling simple, so it’s great for coffee, water, or even mixed drinks. A clever little flask for many purposes.
JOK 4/5

Perfect purse backup for travel

This little bottle is adorable and convenient for carrying in a handbag. I used to bring an old 8oz plastic bottle on flights; switching to this 5oz stainless option avoids microplastic worry. It’s enough for a short wait between services or a brief walk. I noticed the lid becomes cold when filled with chilled water, so some cooling seems to escape there, but it’s very lightweight and fits into my pack with negligible extra bulk.

Tiny but actually helps me hydrate

I struggle to remember to drink during the day, so I bought this tiny flask half as a joke. It fits almost entirely in one hand and tucks into my purse pocket. Because it’s small I actually finish it quickly and feel like I’ve accomplished something. The opening is wide enough to clean easily and to add ice cubes. Its appearance is a bit like a travel spray can but it’s cute and practical — I keep it handy and it’s helping me drink more.
Cosmo 4/5

Very small and limited heat hold

This is the smallest insulated bottle I now own — half the size of my previous 10oz bottle — and its tiny size is its main appeal. It’s easy to carry but five ounces can disappear in a few gulps. I tested how long it keeps things hot: after preheating and filling with very hot water, temperature dropped over several hours, showing that the small volume warms up or cools faster than larger flasks. Good for bedside sips or short bursts of warmth, but don’t expect all‑day thermal performance.

Compact vacuum‑insulated mini flask

This 5oz bottle slips into small bags and pockets easily. Made of 18/8 stainless steel with double‑wall insulation, it’s rust‑resistant and BPA‑free. The threaded lid has a silicone ring that stops leaks so you can toss it into a bag without worrying. The smooth interior rinses clean and the matte finish provides a comfortable grip. Ideal for tiny servings of espresso, tea, or quick hydration.

Lightweight, stylish pocket bottle

This compact bottle is designed to tuck into purses or jacket pockets. Labeled 304 stainless steel, it seems to hold liquids without imparting odors. The color is attractive and it’s very light to carry, making it handy for travel. A size comparison to a 20oz tumbler shows how small and portable it is.
