KikkerlandSquare Reusable Ice Cubes, Made of Plastic (Set of 30) | Filled With Pure Water

So, when I first got these, mine didn’t freeze like a lot of other people who posted. Or, rather about 75% of them froze, and the rest were liquid even after the better part of a week.Then I read a few reviews saying to spread them in a single layer, so that’s what I did. I also packed them in between some other items in the freezer, like frozen vegetables. Next time I checked them, they were all frozen. The cubes may insulate each other against freezing, for some weird reason, so make sure that you spread them out, and if you have a few bags of frozen peas, put them on top. The rest of the cubes should freeze after that.As for keeping drinks cold, I had a jug of water that had been in my car for days (unopened). It’s been around 80 degrees here, so the jug was definitely not cold. I poured a cup of water, put 4 cubes in it, and the water was ice cold in about 5 minutes. Just like any water based cubes, they ARE going to melt at room temperature, and return to liquid as they cool down your drink. In direct sun, you can typically expect any cubes to last 20 minutes tops. Inside a house, they should last about 30-60 minutes before turning completely liquid. If it’s taking you that long to finish a drink, you can always fish out 1-2 cubes, and throw in a couple new ones, or replace the cubes when you pour a new drink.I bought two packs so I could keep pitchers of Margarita and Sangria cold without adding ice, or having to keep it in the fridge the entire party. I just wash mine in a big bowl of soapy water, and then rinse them off in a colander and let them air dry before putting them back in the freezer.

Cute idea for kids who drink their drinks quickly but they don’t hold their cold state long enough for me

To me this product is better than using real ice. My freezer does not make real ice very well, but freezing these cubes makes me not have to miss real ice. I also like the fact that I can use them as an ice pack. I am disabled due to a bad back, leg and foot. Putting these cubes in a cloth and wrapping them around my injured body parts helps a great deal with pain. With the added bonus of they don't melt like real ice cubes do. Easy to clean by hand with regular dish washing detergent.

Love these especially in alcohol drinks because it doesn't water it down and keeps your drink nice and cold! But I use these in just about any drink now 😀 definitely recommend!Only thing is especially in water.. --You don't want to leave them In for hours because you will get kinda a plasticy taste which is expected sense its plastic--

Use these instead of gel packs !!! Buy two packs of 30 each and put them in a gallon size freezer zip lock bag. I first got started with this using 30 in a quart size freezer bag, and I liked the basic result. Supersizing to the gallon bag with 60 cubes is exponentially better. It covers a wider area and is much more flexible and durable than the frozen gel packs. I been using this method on my knee and shoulder and recommend using my cube method. The cubes are thicker than the gel packs, don't wear out or burst a seam, and easily wrap around my knee.

I like these a lot. I throw them in the tippy top rack (I have 3 racks) in the dishwasher with no issues. One of the cubes has some weird black marks on it that do not come off but it doesn't effect the use & when I need more I'll buy these again.

Super cute and fun to use. Really like them for iced coffees or chai teas because they don't water down drinks like normal ice cubes. I use them everyday!

I was hesitant to buy these because I wasn’t sure how well they would work based on reviews from other reusable ice cube products. These definitely work well to cool my drink although it takes a bit longer than a regular ice cube. These also take a longer to freeze and some didn’t freeze at all (I can only assume due to where they were placed in my freezer (on the door) ). Overall, they work well and serve their purpose
