    • 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! 💖

    Well received gift. "Very fun. Perhaps a little heavy on the minty flavors, otherwise enjoy all of them."

    Slime Heaven!

    My kids loved the slime advent calendars. Fun to punch through the numbers and high quality slime. The textures, add-ins and scents were great. A couple were a little stickier than I’d prefer, but we still enjoyed. I recommend!!

    Slime Dreams Do Come True!

    I bought this for my 10 year old daughter for Christmas and it was by far her favorite gift! First, the packaging was adorable! She smiled and laughed as she punched her way through the advent, she even loved the Christmas squishies and extras! Second, the slime, oh my, THE SLIME!!! Hands down the best slime she’s ever played with! The scents and add ins kick things up a notch, but the textures are what will take you to slime heaven! 10/10 would recommend!!! I will definitely be purchasing more slimes from Firefly Slime!!!
