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 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.

fun idea
Sampled

This was a fun idea and my friends definitely asked what was up with them. Kind of cool, but didn't exactly leave me feeling like I had super fresh breath. And some of them had a bit of an after taste

Interesting Product
Sampled

Product was interesting and definitely not something I would have ever tried if I hadn't received a sample of it. I probably will not purchase, however.

Nice to have
Sampled

These were nice to get a sample of because they're the type of things that I just wouldn't spend money on but were nice to try out. Kind of reminded me of high school when people used to use breath spray etc at school dances!

These were awesome

I was a little freaked out by these at first and when I finally got the nerve up to try them they were fantastic!! They really do work and as a smoker it helped to use right before bed since my hubby hates the smell of smoke!!

Fun Breath Mints!
Sampled

I loved these! They are not very strong tasting, but do give a subtle fresh taste in your mouth which is nice. It would not be something you want to use at your desk or something since it is like pop rocks in your mouth, but that makes it fun and different!

Great Freshener
Sampled

I was pleasantly surprised to open up my box and find a breath freshener that was sweet and crackling. I loved pop rocks as a kid, and this adult version with the added benefits are awesome. Highly recommend.

Minty fresh Pop Rocks
Sampled

My friends were pretty confused when I took the bag out and then pretty jealous when they realized they were pop rocks for my breath.
