I spent over two hours researching tub color tablets. I decided on these. (And the first time I purchased these was about a year ago)
The reasons I chose these specific bath color tablets, and have continued to purchase them, are: 1. The ingredients list is minimal in comparison to many other brands 2. Upon placing a tablet into the water it immediately starts to fizz and release the color 3. The colors are bright 4. The colors mix well together to create secondary colors (green, orange, purple) 5. There are large tablets, and smaller tablets (which I find useful for smaller "quick baths" versus larger "long baths") 6. They are simply, fun!
