Great product

Love this product works really well can’t wait to scare with it this year


Awesome product!! Took my costume to the next level!! Shipped quick! Taste was minimal, not aggressively flavored which is nice. It didn’t negatively affect any drinks I had.

Laura Hampton
Exactly what I needed

This stuff is great, it doesn't stain the teeth but lasts long enough to show for a costume. Perfect effect for my Halloween Terrifier costume.

Angelina Metcalf

It was perfect and tastes good too.

Amazing product!!

I was really worried about it staining my teeth, especially the filling I have in my front tooth but it didn't stain permanently at all. As other reviews have said, the extreme color dissipates in a few minutes so you have to reapply it. It was no issue for me.. just kept it in my pocket and reapplied before pictures at my Halloween party. Was very relieved after brushing my teeth and seeing my pearly whites back to their normal color. Overall, excellent product to make you teeth and gums look super yucky. I was Beetlejuice and the brown was perfect!
