The New Tendency Duo includes The Tube Key and The Soap Tray. Learn what each piece does and how to use them to extend your body care products.
Quick answer
The New Tendency Duo is a two-piece set designed to help you get more out of your body care products: The Tube Key rolls tubes flat to use every last drop, and The Soap Tray holds one bar of soap to keep it dry between uses.
Why the Duo matters for your body care routine
If you use Nécessaire body washes, lotions, or serums in aluminum tubes, you know how hard it is to squeeze out the last bit. The Tube Key solves that by rolling the tube evenly from the bottom, so you waste less product. The Soap Tray complements the routine by giving your bar soap a dedicated spot to drain and stay clean.
Both pieces are made from 100% premium-grade stainless steel, so they're built to last and easy to clean. They also support the brand's focus on reducing waste—no single-use parts, just tools you can use over and over.
Frequently asked questions
- What comes in The New Tendency Duo?
- The set includes two items: The Tube Key and The Soap Tray. Both are made from stainless steel and designed to be reused indefinitely.
- How do I use The Tube Key?
- Insert the crimped end of an aluminum tube into the slot on The Tube Key. Press down and slide the key toward the opening of the tube to flatten it. Repeat until the tube is fully rolled and no more product comes out. Use the key on nearly empty tubes to get an extra 2–3 uses out of them.
- How do I use The Soap Tray?
- Place a bar of soap on the tray's raised surface. The stainless steel allows air to circulate underneath, so the soap dries faster between uses. Rinse the tray with water when needed and wipe dry. A dry soap lasts longer and doesn't get mushy.
- Can I use The Tube Key on non-Nécessaire tubes?
- Yes. The Tube Key is designed to work with a large range of aluminum tubes, including those from other brands. It may not work on plastic or laminate tubes.
