Can’t decide on just one flavor? Get all four in the Effervescent Breath Crystals with IsoVoxy multipack.

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.

These packs are like pop rocks for grown ups! They were a nice sample to receive but I don't think I would purchase them.

Nostalgia inducing and effective

I really like these breath crystals. They remind me of when I would eat Pop Rocks as a kid. I liked the taste very much and enjoyed the popping sensation. These are a unique alternative to the traditional breath mint.

Pop Rocks

The product reminded me of Pop rocks. I would say it didn't do more than a mint or candy as far as increasing saliva. Taste was a lemon flavor. I used because it was free but probably wouldn't buy it.

Tasty surprise!

These were like pop rocks that freshen your breath and cleanse your mouth! After swishing around for about a minute, I felt very refreshed! Such a great idea when you don't have time to brush your teeth.

Minty Pop Rocks
Sampled

The crackling is quite intense so be ready for it! I didn't mind it though and they made my breath extra fresh. Fun twist to regular breath mints.

Pop-rocks for grown ups!
Sampled

These amazing breath crystals are a burst of fresh breath! I love gum, but I'm not a pretty gum chewer by any means! These awesome packets are fun for a minute or two, and then leave you refreshed without making you look unprofessional smacking a piece of gum for the next hour.

Interesting

I religiously buy and keep "Whisps" in my purse, which are like mini tooth brushes that freshen your breath. So, i was really excited to get this product in my box and try something new. Overall, i was pretty happy with these! Super convenient for after a garlicy lunch, or wake up somewhere other than your toothbrush ;) They did leave a bit of an odd taste in my mouth, and thats the only downfall.
