Theses beads are used to make the hottest trend in Slime right now! 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 beads on the market. The beads are made of a lightweight straw material that creates tons of air pockets within the Slime when playing with it, which is why it produces the most satisfying ASMR your ears will ever hear.
