Frequently Asked Questions

Is it easy to use?

Yes. There's no new flossing technique to learn — you floss exactly the way you already do. The only thing to pick up is how to wrap the floss onto the holder, and that takes seconds. We've included step-by-step schematics and a short video to walk you through it.

Does the holder work with any floss?

Yes. Load whatever floss you already like — there are no cartridges or proprietary refills. You just use your own floss, about 20 cm per session.

Does it hold the floss taut?


Yes. It's a proven design, refined and validated by thousands of users, that keeps the floss firm and taut through every pass, so it won't sag or slip the way flimsy holders do. And if you like even more tension, just wrap the floss one extra loop around the post — a quick adjustment that tightens it further. Taut floss is what actually cleans between your teeth.

How often do I need to refill?

There are no refills to buy — you simply reload your own floss. Each use takes ~20 cm, so a standard 40 m spool lasts around 200 sessions. You only ever replace the floss, never the tool.

Is it safe to put in my mouth?

Yes. It's food-grade 304 stainless steel — non-toxic, non-porous, and safe for everyday use in your mouth. (The gold version's titanium-nitride coating is biocompatible too — the same finish used on surgical instruments.)

Is it hygienic?

Yes. It's a single, non-porous piece of steel with no seams for residue to hide in, and you use fresh floss every time. Rinse after use; it's dishwasher-safe for a deeper clean.

Will it chip or damage my teeth?

No. It's designed to be gentle: at just 12 g — around half the weight of a spoon — with smooth, rounded contact points. Even an accidental knock against your teeth won't chip or harm them.

How long will it last?

With proper care, it's built to last a lifetime. Because it's cut from a single piece of 304 stainless steel — with no moving parts to loosen or wear down — it keeps its shape and performs like new for years. The only thing you'll ever need to replace is the floss.

How much plastic do I save?

Used twice a day, one holder replaces roughly 7,300 disposable plastic flossers over 10 years — all kept out of landfill.

Ordering and Shipping

What's the lead time for orders?

Orders ship within 1–2 business days; delivery then takes about 2 - 27 business days depending on your location.

See our full shipping policy for details.

How can I track my order?

Once your order is shipped, we will provide you with a tracking number via email. You can use this tracking number to monitor the progress of your shipment and estimate the delivery date.

Do you offer local pickup?

We don't offer local pickup at this time. If this is something you'd be interested in seeing in the future, let us know!

What's included in the shipping cost?

Your shipping total covers three things:
Carriage — the cost of physically shipping your order from Canada across the border to your door.
Import duties — tariffs the government charges on goods entering the country.
Customs clearance — handling your order as duty-paid so it moves through customs smoothly with no surprise fees or brokerage charges when it arrives.

We pay all of this upfront on your behalf, so the price you see at checkout is the price you pay — nothing extra at delivery.
