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!!!
