Do the maths
Why we call it the No Brainer.
Here's exactly what's in the box, and what each piece costs on our site today.
Build your box
Pick your two strip flavours.
Everything else in the bundle is the same. Choose the combo you'll actually enjoy using.
28 strips total. Same 6.9% formula in every flavour — pick on taste alone.
In the box
Five things. One delivery.
Two of them do the whitening. Three of them make sure it lasts.
The Platinum Kit
Our best-seller. A 6.9% hydrogen peroxide formula and the BLK Light 2.0 mouthpiece, with a built-in 25-minute timer. Two pens in the box, 30+ treatments in total. This is the one that does the heavy lifting.
Platinum Strips × 2
Two full packs — 28 strips — for the days you can't be bothered with the kit. Fold, wear 25 minutes with the light, done. Mix two flavours or double up on your favourite.
LED E-Mirror
Our smallest product, our biggest energy. Proper white light so you can see your actual shade — not your bathroom's version of it.
Tongue Scraper
Ten seconds a morning. Whiter teeth are only half of a clean mouth — this is the half everybody forgets.
Glass Straws
The cheapest way to protect what you just paid for. Coffee, wine and Coke Zero go straight past the front teeth.
That's $364 of gear, in one box.
You pay $278 and keep the difference. No code to remember, no timer counting down — this is just the price.
The comparison
Three ways to whiten.
Same goal. Very different bills.
Our own Ponsonby studio, for a single appointment. Brilliant — but it's one visit, and you have to get there.
Kit, two strip packs, mirror, scraper and straws, all added to the cart one at a time at full price.
All of it, in one box, with 58+ treatments inside. Works out around $4.79 a treatment, at home, in your own bathroom.

How it works
Twenty-five minutes. That's the whole routine.
Load the pens, wear the light
Paint the gel across your front teeth with the Platinum pen, pop in the BLK Light 2.0 mouthpiece, and set the built-in timer going.
Give it 25 minutes
Watch something. The light shuts itself off when you're done. Most people run a session every day for the first week, then top up as they like.
Keep it up with strips
Travelling, or just tired? Fold a strip over your teeth instead. 28 of them in the box, so maintenance is already sorted for months.
Before you ask
The honest answers.
Is this actually a good deal, or is the "value" made up?
Every price in that list is what the item sells for on whiteningco.nz right now — $159 kit, $69 a strip pack, $19 mirror, $19 scraper, $29 straws. Add it up and it's $364. You pay $278. You can check every one of those prices on our site.
Will it actually whiten my teeth?
Both the kit and the strips use a 6.9% hydrogen peroxide formula, and most people see a visible difference within a few sessions. If you complete the full treatment as directed, work with our team along the way, and still see no visible result, our 100% Money-Back Guarantee applies — claims within 60 days of delivery. Full terms are on our FAQ page.
What if I have sensitive teeth?
Plenty of our customers do. The usual advice is to space sessions out rather than going daily, and to stop for a couple of days if you feel anything. Our whitening specialists answer this one constantly — message the team before you start and they'll set your routine up around it.
How long will the box last me?
There are 30+ treatments in the kit and 28 strips alongside it — 58+ sessions all up. For most people that's a full whitening course plus the better part of a year of top-ups.
Is this a subscription?
No. One box, one payment, nothing recurring. Afterpay and Klarna are available at checkout if you'd rather split it.
Do you ship to Australia?
Yes — tracked, via NZ Post standard or DHL express. Standard delivery usually lands in 3–5 business days, express in 1–3. Inside New Zealand it's free over $150 (so this bundle ships free) and normally arrives in 1–3 business days.
Can I pick two of the same flavour?
You can. Double Mint and Double Peach are both there, along with one of each. Arctic Spritz is out of stock at the moment — it'll be back.
Last thing
$364 of whitening. $278.
No code, no countdown, no "ends midnight". It's just the price — and the three extras are in the box either way.
Complete the full treatment as directed and work with our whitening specialists along the way. If you still see no visible result, you get your money back. Claims within 60 days of delivery — full terms on our FAQ page.
