Unlike paints, it does not become cloudy when mixed. For playing shopkeeper: "Please give me some juice♪" "How about orange juice with pink and yellow?" "Grape juice with yellow and blue is delicious♪" You can play like this ❤ What color will it be when you mix this color and that color...? The color changes when you change the amount... You can also do experiments like this ❤ Fold Japanese paper and dip it in ink, and you'll have colorful patterned napkins ❤ It's "washable ink" that easily washes off clothes. It comes in a container with a dropper tip, so you can dispense the ink drop by drop, making it easy to control the amount, and you can also dye Japanese paper. A full 8ml bottle can dispense about 150 drops. (Cotton and polyester are easy to wash off, while wool, silk, and nylon are more likely to stain and harder to wash off. Also, even on fabrics that are easy to wash off, if left for a long time, it may become difficult to remove.) Since they are used, the bottles are not full of ink. Three of the pink ones are about half full. The set on the right has ink levels close to unused. The set on the left is a collection of used items. Please check the photos for details. The caps are closed, but ink may leak during transport due to strong shaking or impact. Containers for dropping ink and Japanese paper are not included. Please consider this if you are interested in colored water play, which is fun and educational for developing color sense.
