300 Count - New Eco-Friendly Container - The Original Fizzy Color Changing Tablets - Fun Educational Bathtime Activity for Kids, Safe, Non Toxic, Non Staining, Soap and Fragrance-Free

I purchased these colors last year for my kids who are a bit older at 8-10 years old but they both love picking out the tabs and seeing what color the water will turn. Normally, my kids each take at least one bath a week. Which means we have had plenty of opportunities to try out these colors. I haven’t had any issues with tub staining or skin staining. Even if your hands get wet and you touch the tab, you won’t have a color stain on your palm. I also have harder water and still haven’t had issues of the color grabbing any hard water build up anywhere.My kids have loved these so much they are asking to get another bottle this year for Christmas. We haven’t used up the entire bottle yet from last year (I set a limit of 4 small tabs or 2 big tabs) so we have some left but no big ones. So I will be purchasing again!I do wish the bottle came closed up so it doesn’t spill all inside the shipping box. Maybe this year!Update- purchased and received again! This time the container had two stickers holding the lid on and they held! Still had some dust but much better than not having anything holding the lid like last year!

As you can see from the attached photo, I opened the mailbag and the bath pellets were all loose inside, as the package had broken. The size of these colour drops is much, much smaller than I expected, they're the size of a small fingernail. I'll post another review once I've dropped one in the bath.

My son absolutely loves these, he is not even 2 yet and has already learned color theory largely thanks to these. He knows that yellow and blue make green, blue and red make purple, and yellow and red make orange. I still have to hand him the colors (otherwise he would dump the whole box in!) but he chooses what color he wants and tells me what he needs. I love the different size options to create a variety of shades. No problems with the tub getting dyed (but we have a ceramic tub) or skin. and sometimes my son will hold one of the colors between his fingers as it dissolves, and by the end of the bath his fingers are not colored. My son also has a history of sensitive skin and we have not had any issues with this product. I know some reviewers are frustrated that this bottle opens so easily, but for me it not being a plastic bottle is a plus. I've not had it arrive spilled all over the place though either, but if i did I still think its worth it. I would say all they probably have to do is apply some tape to the sides and it would be solid, but that's up the product makers! We have repurchased this item about 3 or 4 times already and is a big hit/staple in our bath routine.

Just order a few of these at a time because you’re going to use them and you’re going to want to share with other parents. They have super vivid colors that leave absolutely no residue on towels or tubs or kiddos. Super fun and makes bath time enjoyable.

I give this 4 stars only because these come in 2 different sizes: the larger ones are about the size of a penny with about 1 cm thickness, while the little ones are the size of a watch battery with about .25 cm thickness. I'm not entirely sure why the small ones are even necessary and it feel like there could have been more larger ones instead. I can use 2 of each large color to make a vibrant bath water, but I have to use at least 10 small ones to achieve the same. Seems wasteful. These make the water slightly oily so I only use them on days we use soap, otherwise my kid will have a slight sheen when done with bath. Other than that these are by far the best ones I've come across.
