Review: Great Size for my Needs - I purchased this smaller (12oz) water bottle because I already have a large bottle (32oz.) that I use around the house. But I needed something smaller that would be light weight and more portable when going to the store or on an errand, a bottle that would fit in my purse and in my car cupholder. And I prefer to travel on flights with a smaller bottle too. This one fits my needs. Is good quality, easy to use, great size for travels and I will be more likely to drink more water because it’s handy when I’m traveling. That makes it 5 star from my perspective. Just a note: The strap is great for carrying in hand but not made for strapping to a backpack or purse strap. To make that happen I’ll purchased a carabiner. Review: This bottle is perfect! - Although this is listed as being a size for children, I am a normal sized adult woman with arthritis pain in my hands and fingers. This bottle is the perfect size. It holds 12 full ounces and has a sturdy, totally leak-proof lid. I often use the little cocktail size ice cubes that my refrigerator makes. With those little cubes, this bottle keeps my water cold overnight or all day on a long drive. It’s an ideal water bottle! ## Features - DETACHABLE CARRYING STRAP - you can remove the string for individual cleaning. When your kids is out and about, the bottle can be hung on the backpack or on your fingers instead of holding it all the time, so your palms and wrists will be relaxed. - SAFE TO DRINK - Mollcity's insulated water bottles are made from BPA-free, phthalate-free, non-toxic, rust-free 18/8 stainless steel. The water bottle won't leach any harmful substances into your drink, so kids can sip every sip of their favourite beverage with confidence. - LONGER INSULATION - Double-layer vacuum insulation technology combined with the classic Coke-shaped sip bottle keeps drinks cold for 24 hours or hot for 12 hours, ensuring drinks stay fresh and cold all day, right down to the last sip. - NO LEAK& NO SWEAT - The 100% leak-proof lid allows the water bottle to be kept safely in the backpack without spills or mess. Vacuum technology makes the water bottle sweat-free and even when the glass is filled with ice water, condensation does not appear on the outside. - INDEPENDENT USE - The compact water bottle fits perfectly in a child's small hands and is easy for the child to grip. The threaded top of the lid adds to the grip and allows children to easily open the lid and hydrate in time, encouraging independent drinking. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BLNGVYN5 | | Additional Features | Cold 24 Hours, Double Wall, Hot 12 Hours, Leakproof, Lightweight | | Age Range (Description) | Kid,Adult | | Age Range Description | Kid,Adult | | Best Sellers Rank | #4,986 in Kitchen & Dining ( See Top 100 in Kitchen & Dining ) #104 in Insulated Bottles | | Brand | Mollcity | | Brand Name | Mollcity | | Cap Type | Screw Cap | | Capacity | 9 Fluid Ounces | | Color | Stainless Steel | | Customer Reviews | 4.6 out of 5 stars 1,622 Reviews | | Included Components | Lid | | Is Oven Safe | No | | Is the item dishwasher safe? | No | | Is the item microwaveable? | No | | Item Dimensions W x H | 1.14"W x 2.36"H | | Item Height | 6 inches | | Item Weight | 0.3 Kilograms | | Material Type | Stainless Steel | | Number of Items | 1 | | Product Care Instructions | Hand Wash Only | | Recommended Uses For Product | Water | | Special Feature | Cold 24 Hours, Double Wall , Hot 12 Hours, Leakproof, Lightweight | | Theme | Sport | | Unit Count | 1.0 Count | | With Lid | Yes | ## Images ![9 oz Water Bottle for Kids-Stainless Steel Vacuum Insulated Sports Flask Leak Proof Small Water Bottles for School (Silver) - Image 1](https://m.media-amazon.com/images/I/51vSSf-E9fL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Size for my Needs *by K***N on January 24, 2026* I purchased this smaller (12oz) water bottle because I already have a large bottle (32oz.) that I use around the house.
