Soft, sensory slime parties styled like a couture birthday — pink, purple, blue, and pure joy.
The experience
We bring the mushy science to your celebration — curated textures, pastel setups, and guided play that feels premium without losing the giggle.
Butter, cloud, and swirl textures mixed fresh — glossy, stretchy, and endlessly pokeable.
White linens, soft florals of color, and a setup that photographs as beautifully as it plays.
We run the lab so you can sip, snap photos, and watch the birthday glow happen.
Packages
Every party includes a host, all materials, take-home slime, and a clean-up crew for peace of mind.
