This slime features one of our customer-favorite and most beginner-friendly slime texture that is topped with assorted rainbow sprinkles inspired by a birthday cake.

Butter slimes, aka clay slimes are made with our signature clay slime base for marshmallow-like texture. Butter slimes are known for being more holdable, pillow-y, spreadable, and soft. All Fireflyslime butter slimes are specially formulated to be easily inflated (more than 2x it's original size) by stretching to incorporate air bubbles and easy to deflate back to it's original size by squeezing all of the air back out. 

Scent: Vanilla Buttercream

  • Congratulations on your new slime! To ensure it stays fresh, fun, and enjoyable for as long as possible, here are some simple care tips:

    🧼 Wash Your Hands

    Always wash your hands before and after playing with your slime. Clean, dry hands help prevent germs, oils, and dirt from transferring to the slime, which can make it sticky over time.

    🫙 Store It Properly

    Slime can dry out if exposed to air! Always keep it in the airtight container provided, ensuring the lid is fully closed after each use.

    ⚠️ Play With Care

    Avoid letting your slime touch hair, clothing, carpet, or any porous surfaces. It’s best to play with your slime on a clean, smooth surface.

    ☀️ Avoid Heat and Sunlight

    Slime can melt if exposed to direct sunlight or high temperatures. Keep it in a cool, dry place when not in use.

    📦 Care Card Included

    Don’t worry—your order comes with a printed care card for easy reference! Keep it handy to help troubleshoot any slime issues.

    Enjoy your slime, and thank you for supporting fireflyslime! 💖
