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!

A little pricey
Purchased

I got this in the Honey Mint version, and it tastes a little weird. I've heard the other flavors are better. It's also a little pricey, but nice if you have money to spend and want a breath freshener and poprocks duo...

I think I'm sticking to gum/mints.

Fun yet strong
Purchased

These are great and fun mints, but the peppermint flavor can be a little strong. I put these in my Welcome Bags for out-of-town guests for our wedding! They were a hit.

Minty PopRocks Yeah!
Purchased

Half a serving is enough to make my breath minty fresh. In fact I had to share them at a meeting I went to and everyone found them fun, refreshing, and good. Excellent item to keep handy.

Total gimmick.
Purchased

All these did was clump together and get stuck in my teeth! They were obnoxiously difficult to swish around in my mouth, and I felt disgusting afterwards and in no way as if my mouth was any cleaner. Don't waste your money!

Pop Rocks for big kids

I love the peppermint flavor. Works well when you need a quick breath fresher. The individual packets make a nice stocking stuffer.

Fun and great for coffee breath!
Purchased

Pleasant surprise. Much better than gum or harsh sprays. Love the intensity of the pops and it tastes good too!

Yummy
Purchased

I really enjoyed the pop rocks feel of this product. Although a little pricey for the fun factor. Had to hide them from my husband.

It was kind of overwhelming putting the whole packet in my mouth so I only used half. I decided to use the other half for later however when I did they no longer worked. The pop-rock like experience was gone. The breath freshening part still worked though.
