    Hi! My cousin ordered me one of your birthday pack slimes for my birthday. I just wanted to say thank you so much! Extremely good quality and it’s lasting unlike other slimes I’ve bought online in the past :)

    Hi Sienna my daughters slime arrived today. Firstly your delivery is so fast. You make such beautiful slime that smells so good and it’s not messy at all! From a mum that dislikes slime this is huge. Thanks again.

    Wow ! Your slime was on the top of the list for my sons birthday and I now understand why. Your packaging is beautiful and fun. He has been playing with his slimes for over 2 hours. Thank you!
