Our love letter to drinkware.

No nonsense. No fuss.
No messy environmental impact.

Hand-washable, dishwasher-safe, cupholder and cabinet ready*.

Multi-Liquid
Open, closed, or infuse.
The ShellLock™ comes in three different styles, so you can have hot and cold beverages in the same or separate TurtleShells™.
Hot or cold, multi-liquid, and stackable.
Infuse with your favorite fruit, tea bags, or coffee with our patented ShellLock™ Screen.
All taste and no waste.
Scrub Away
TurtleShells™ are open-ended and easy to clean. All you need are three fingers, a sponge, and some soap.
No wire brush, no hydrogen peroxide tablets, no smell test needed.
Plus, they're dishwasher-safe. We made them so easy to clean you'll never have to reach for single-use plastic again.
Any Cabinet
Gone are the days of thinking sideways. No more struggling to fit bottles on a shelf.
TurtleShell™ replaces bulky, single-function drinkware and saves space in your cabinet.
Grab a pack of TurtleShells™ and say goodbye to washing your clunky bottle or reaching for single-use plastic. There's plenty of room for TurtleShells™ in your dishwasher, too.

Hot or Cold
Double-walled insulation for when you're on the go and need options.

TurtleShells™ are made from 100% borosilicate glass and food-grade stainless steel.

No matter how extreme the temperature change, from freezer to fire, our TurtleGlass™ will not crack.
Two Becomes One
With our patented ShellLock™, two cups combine into a TurtleShell™, so you can take them on the go.

Say goodbye to single-use plastic and create a new ritual with Niiche modular drinkware.

Zero Plastic
70% of 'BPA-free' plastics still leach toxic chemicals into water.
These xenobiotics are carcinogenic and harm reproductive health.
TurtleShells™ are made exclusively of food-grade stainless steel and borosilicate glass, so you can have peace of mind.
Truly Modular
No more Tupperware effect. One size to rule them all. With a three inch diameter, all TurtleShell™ caps and ShellLocks™ are interchangeable.
Gone are the days of having to decide between glass or stainless steel.
A modular system that takes the guesswork out of drinkware.
Mix and match. Or, one and done.

Measuring Cup Approved
From cooking to cocktails, all of our patented shells have a 2 ounce measuring cap. And, there's a volumetric marker placed at the exact center of your shell.
With TurtleShells™, you'll always have the tools you need for day-to-day measurements.
Any Cupholder
Gone are the words "too tall" and "too wide." With our cupholder-ready 3-inch diameter, your Turtleshell™ is ready to go wherever and whenever you are.
Seltzer Approved
Our double-layered insulation keeps small canned beverages cold without sweating and provides a snugger fit in cupholders.
