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.

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.

not worth buying

I don't think this actually freshens breath. I think this product is a Complete hoax. I would never buy this product.

Great

This is a great product. I only withheld the fifth star because it is a bit odd. They work well and are pleasant but no more so than a mint.

Loved this product. Fresh and tasted great. The product actually did what it said so I was thrilled when I used it. Wish it had been a larger sample size.

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
