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.

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.

Odd
Sampled

These are a really interesting concept but I can't see them catching on in the real world. The novelty is fun but they are so much more disruptive and inconvenient than a piece of gum or a normal mint.

I LOVE THESE!!!
SampledPurchased

I'm totally hooked on these breath mints! They work great and are super fun. They also take care of even the nastiest of odors, quickly.

Strange Product!
Sampled

This is a strange product. I decided to use one on a friend as a joke. I told her they were mints and to put them in her mouth. Bam! Freaked her out a little. These things don't work. It tastes like sugar and any taste that is supposed to freshen your breath fades quickly. Would not buy this product.

enjoyable

I enjoy these, good flavor and quite refreshing. I enjoy the pop rocks affect. Both my husband and I got them in out boxes. I keep some in my purse and car for on the go.

Bizarre, in a good way
Sampled

These are pretty weird. Minty pop rocks. Can't really tell if they are more effective than regular mints, but I would say that they are definitely less effective than gum. Still absolutely some novelty factor here. Would consider buying more--but I'm kind of on the fence. The form factor is also not all that great for tossing in a bag and using while on the go.
