ConBlom Color Changing Cups, 5 Packs Reusable Iced Coffee Travel Mugs 24oz Plastic Cold Cups BPA Free Magic Tumbler with Straws & Lids & Brushes for Kids Adult

Kids loved things and makes them drink more so they change colour

Perfect for large drink haulage. Im terrible at not drinking enough throughout the day. These are ideal, can be filled with ice and the straw stops the immediate cold pain in my front teeth. They fit perfectly in my car cup holder and I know that if I drink 3, Ive covered my minimum 2l daily fluid intake. The only negative is that the second set of mine don't change colour when it's got ice in. It's not important to me, so I've not marked down, but if you buy for the wow factor with kids, be aware. The first set however, were colour changing and fine until an unfortunate incident.

They do not change colour. Complete con. Do not buy.

Colour stays the same had no reply’s from the seller

They are good quality for the price.

They do change colors, but the drink has to be so cold it's near undrinkable. It's disappointing as the product page would have you believe the drink just needs to be cold, not frozen. The colors are also nowhere near as vibrant as depicted.The first image I've attached shows the cups with cold water, and the second with water straight out of the freezer.

Perfect alternative to the expensive branded cups of the same size and make. Works fine, I would not put it in the dishwasher.
