Theses beads are used to make the hottest trend in Slime! They make the most crispy, crunchy, bubble-poppy Slimes in the world. You can't quite replicate the sounds these beads make with other types of Slime ingredients. The beads are made of a lightweight straw material that creates tons of air pockets during play, which is why it produces the most satisfying ASMR your ears will ever hear.
