How It Works
Three steps. No excuses.
01
Drop in the liner
Place the plant-based biodegradable liner inside the glass vessel. It seats flush against the walls and base, creating a sealed inner surface between your food and the glass.
02
Prep, seal, microwave, go
Fill it, seal the liner closed, and refrigerate or microwave directly. Leak-proof through your bag. Microwave-safe at the table. The liner does the work the glass can't.
03
Peel. Compost. Repeat.
When you're done eating, peel the liner out in one clean pull. Toss it in your compost bin. The glass vessel rinses clean in seconds — no residue, no staining, no scrubbing.
The Inner Liner System
Cleanup was always the problem.
The biodegradable liner drops inside the glass vessel and seats flush against the walls. It's the surface your food actually touches — sealed, leak-proof, and microwave-safe. When you're done, it peels out in one pull and goes straight in the compost.
Made from cassava starch and cellulose. No microplastics. No PFAS. The glass stays spotless.

Why It's Different
No compromises.
Plant-Based Inner Liner
The liner seats inside the vessel and contacts your food directly. Made from cassava starch and cellulose — microwave-safe, leak-proof, and fully compostable in 90 days.
Borosilicate Glass Vessel
The outer vessel is built to last years. Thermal-shock resistant, dishwasher-safe, and structurally inert. The liner protects it from staining and residue every single use.
Microwave & Leak-Proof
The sealed liner is microwave-safe and holds liquids without leaking. Heat your meal directly in the container — no transferring, no extra dishes.
One-Pull Cleanup
Peel the liner out in a single motion. The glass underneath is clean. No soaking, no scrubbing, no stained walls. The liner composts in 90 days.
"Your container should be as disciplined as your diet."
— HannahWhy It Exists
Hannah was tired of scrubbing containers.
After years of coaching clients through meal prep, the same complaint came up over and over: cleanup. Stained walls. Residue in the grooves. Containers that smelled like last Tuesday's chicken no matter how many times you washed them. Hannah wanted a system that matched the standard she held for everything else — clean, intentional, and built to last.
The Clarissa Container is that system. The glass vessel is permanent. The biodegradable liner sits inside it, contacts your food, seals it in, and microwaves with it. When you're done, you peel the liner out in one pull and compost it. The glass is spotless. No scrubbing. No staining. No guilt.

They don't lie.
"The liner concept is genius. I used to dread cleaning my meal prep containers — now I just peel and compost. The glass looks brand new after 3 months of daily use."

"I was skeptical about microwaving the liner but it heats perfectly and doesn't leak at all. Carried it in my gym bag all week — not a single spill."

"The one-pull cleanup is real. I meal prep 6 containers on Sunday and cleanup used to take 20 minutes. Now it's 2. This is the future of meal prep."
