Textures range from clear, stretchy premade slime and translucent squishy slimes to light, airy modeling dough and creamy, buttery putty. Mix-ins (like beads or crunchy add-ins) can create crunchy or textured feels.
Age recommendations commonly start at 3 years, with many products labeled 6 years and up. Specific guidance varies by product, so check the individual listing for exact age recommendations.
Many items are described as non-toxic. Some modeling dough listings explicitly state they are free of gluten, egg, milk, peanuts and soy. Several listings also include CPSC small-parts choking-hazard warnings—check each product’s label for full safety and allergen details.
Kits include mix-ins described as texture changers and visual add-ins—for example, clay (used for butter slime), bingsu beads (for crunchy slime), sprinkles, glitter, glow-in-the-dark stars, fishbowl beads and small themed figures.
Some products are premade slime that come ready to play straight from a bucket or tub, while others are labeled as air-dry modeling dough or air-dry clay intended for molding and sculpting.
