Birchbox Breakdown

If you miss spending your summer days with nothing but time to kill and a packet of Pop Rocks, then you’ll be happy to find these Effervescent Breath Crystals, which attack halitosis with the ferocity of that sweet, crackling candy. The science rests on a mix of bacteria-fighting ingredients that, when in contact with germ-filled teeth and gums, erases the effects of embarrassing odors caused by things like coffee, onions, and garlic with a series of mini-mouth explosions.

How it Works

Unlike gum and breath mints, which only mask bad breath, these teeth-cleaning crystals pack zinc and IsoVoxy to kill odor-causing bacteria. Once dissolved, they leave a fresh scent courtesy of natural peppermint flavors.

How to Use

Pour the contents of an individual pack into your mouth and swish the crystals around, rubbing them against teeth and tongue. Let them dissolve or swallow and enjoy peppermint-fresh breath!

Peppermint: Isomalt, Carbon Dioxide, Xylitol, Natural Peppermint Flavor, Zinc Gluconate, Sunflower Oil, Sucralose.

Spearmint: Isomalt, Carbon Dioxide, Xylitol, Natural Spearmint Flavor, Zinc Gluconate, Sunflower Oil, Sucralose.

Lemon: Isomalt, Carbon Dioxide, Xylitol, Natural Lemon Mint Flavor, Zinc Gluconate, Sunflower Oil, Sucralose.

Honey: Isomalt, Carbon Dioxide, Xylitol, Natural Honey Mint Flavor, Zinc Gluconate, Sunflower Oil, Sucralose.

Just ok

Great concept, but the flavor left my mouth a little more dry than refreshed. I would like to see more flavor options.

Just okay

Too pricey, didn't care for the flavor or feel in my mouth. I prefer gum which is more affordable and convenient. Sorry to say I wouldn't buy it ever.

It was alright

It was alright but not really my cup of tea - I'll stick to mint gum for the time being.

Icky

I don't like the way my mouth feels after using this product. Fortunately I'll be seeing the dentist this week because I think it hurt my teeth and gave me a cavity. Gum is better for breath freshening.

amazing

These little crystals are great! I wish Birchbox didn't always sell out of the items I want. This seems like it always happens to me :(

Pop Rocks meet Fresh breath?

Not so sure about this one. It was kind of a weird pop rocks sensation but overall I don't believe it did any breath freshening to the point where I would buy it.

Yuck!

Ever wanted to know what cough drop flavored pop rocks would taste like? Well here ya go! I had the honey mint one and it was disturbing. Not sure why you would want to pay so much for this product...its just a bad idea, I'm sorry. Get altoids or gum instead

So cool!

I loved the samples in my May box! A little grown-up version of one of my favorite candies! The price point is a bit high though for a breath freshener.
