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.

Meh

I didn't like these at all. The taste was weird and it is not something I would ever use on a regular basis. Avoid these and don't waste your money

Fun for the novice of it
Sampled

This is basically gum, but in Pop Rock form. So, it was fun the first use, but as it didn't do anything chewing a piece of mint gum can't handle (fresh breath for about 30 minutes) I don't think I'd ever buy it. Gum is easier, and more discreet, and just as effective. I will however, be purchasing some pop rocks...

They freshened my breath
Sampled

I think these were so odd, pop rocky and what chemicals did I just introduce willingly into my body - nearly everything else used to effectively freshen breath is spit back out .... I guess this is like mysterious semi-freaky breath mints in pop rock form... Would never purchase

I love these little crystals. I saved a packet for my wedding day and wasn't disappointed. I felt fresh and clean. And the bubbly pop rocks feeling was to die for

I don't know why these would come in the box. They don't melt very well and are ackward overall.

Minty Fresh
Sampled

This is a convenient way to freshen breath quickly especially after eating some very strong foods or drinking coffee. I'm not sure I'd buy this after trying it out because I could just brush my teeth or chew some gum. I also use a wallet/clutch and don't have much space. Maybe when carrying a larger bag.

Use em if you got em
Sampled

One pack seemed a bit much to shove in your mouth all in one go, it's the better option though since they get chunky over time. At least it's help your breath out.

Cool but unnecessary
Sampled

These breath crystals have a nice taste and are a fun way to consume mouth-cleaning products. Having said that, I don't see these being something you buy in bulk to carry around. Just not particularly practical for what they are.

Interesting

These were like minty pop rocks. Really interesting spin on breath mints. Seemed to last a while, too. Overall I liked them but they were weird at first and took some getting used to =)
