Restocking shouldn't come with extra waste. Each refill spool skips the packaging of a brand-new case, so every reorder stays just as plastic-free as your first one.

Gentle Between Teeth

Soft, smooth silk glides comfortably between teeth to help remove buildup without the harsh feel of traditional synthetic floss — the same gentle feel, spool after spool.

Naturally Biodegradable

Made with natural silk and plant-based candelilla wax, each refill spool is designed to break down more naturally than plastic-based floss, keeping your routine low-waste with every restock.

No new jar, no extra clutter. Every refill spool is sized to drop straight into your existing Seek Bamboo glass jar, so you can restock in seconds and keep going.

Miles of Plastic floss end up in our landfills every year.

Here’s something to chew on—traditional plastic floss sticks around way longer than it should. Once tossed, those little strands don’t just vanish; they pile up in landfills and waterways, adding to a mess our planet doesn’t need. But there’s a fresher way to floss! Switching to eco-friendly floss options means you can keep your smile clean and give the earth something to grin about. Because good habits should be good for more than just your teeth.

The Unspun Story: Refill FAQs

Everything You Need to Know About Our Silk Floss Dental Floss

What is silk floss, and how is it different from plastic floss?

Silk floss is a fine, silk-textured thread coated in wax to help it glide between teeth. Traditional floss is nylon coated in a synthetic PTFE plastic — this floss is coated in plant-based candelilla wax instead, with no synthetic plastic coating.

What is candelilla wax, and why is it used on the floss?

Candelilla wax is a natural wax harvested from the candelilla shrub, used as a plant-based coating that helps floss glide smoothly between teeth. It replaces the synthetic PTFE coating found on most plastic floss — the typical source of PFAS chemicals in conventional floss.

Is silk floss compostable or biodegradable?

Yes. Made with natural fibers and plant-based candelilla wax, this floss breaks down far more naturally than nylon or PTFE-coated floss, which doesn't decompose in landfills.

How many meters of floss are on each spool?

Each spool contains 30 meters of silk floss — enough for roughly a month of daily flossing, which is why refills come in 2-spool (2-month) and 4-spool (4-month) options.

How long does one spool of floss last?

One spool lasts about one month with daily flossing. That's why refills come in a 2-spool (2-month) option and a 4-spool (4-month) option.

What's the difference between the 2-month and 4-month refill option?

Both contain the same silk floss — only the quantity differs. The 2-month option includes 2 spools; the 4-month option includes 4 spools at a lower price per spool.

Will these refills fit my existing Silk Dental Floss jar?

Yes. Every refill spool is sized to drop directly into the Seek Bamboo reusable glass jar — no new holder needed.

How do I load a new spool into my glass jar?

1. Unscrew the metal lid.

2. Remove the empty spool.

3. Drop in a new spool.

4. Thread the end through the lid opening.
