Hi! I'm Sienna and I'm 16 years old. Welcome to my online slime store!

I love to create slime and gift packs for people of all ages. Our slime is proudly made in Australia and each set is carefully decorated with care. We love to make receiving and playing with slime FUN and we are known for our quirky additions that make Slime by Sienna extra fun !  

Our slime is carefully designed, decorated and produced with care from the design right up to packaging and delivery.

We pride ourselves to a very quick turnaround as all our orders are made and shipped within 24- 48 hours of receiving the order.

We are the home of no mess slime, which people love to play with at home, take away or at parties! 

We host slime birthday parties in Melbourne and also provide 'Do It Yourself' Birthday Party Boxes for those who want to host their own.

Slime by Sienna is a Melbourne home based business run by Sienna herself.

We ship our slimes Australia wide and New Zealand.

    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!
