Prep every week. Wash every day. Never buy another meal prep container again.
Your Forever Prep Box is built to keep up with years of cooking, stacking, packing, reheating, and washing. That's why every box is backed by our Lifetime Meals & Washes Warranty.
Buy it once. Prep for life.
Wait, can you really microwave stainless steel?
Yes! Forever Prep Box is designed with a smooth, rounded-edge profile to help reduce electrical arcing in compatible microwaves. Unlike conventional metal containers with sharp edges, it's engineered for convenient reheating.
Will it leak in my bag?
The tempered glass lid features a snug-fitting silicone sealing rim designed to help keep your meals contained while you're on the move.
For soups, sauces, and other liquids, always keep the container upright.
Is 33.8 oz big enough for a full meal?
Absolutely. With 1,000 mL (4.2 cups) of capacity, there's room for a satisfying meal of protein, carbs, and vegetables.
Whether you're prepping lighter lunches or hearty, protein-packed meals, it's designed to accommodate a wide range of portions without unnecessary bulk.
Is it actually lighter than glass containers?
The stainless steel body is designed to offer a more practical alternative to heavy glass containers, without the worry of shattering.
It's a convenient choice for carrying multiple meals to work, the gym, or wherever your day takes you.
Is the entire container plastic-free, including the lid?
Yes! The container uses a stainless steel body and a tempered glass lid with a food-grade silicone sealing rim.
No plastic food-contact surfaces, so you can store your homemade meals without relying on traditional plastic containers.
Does food stick to stainless steel? Is it difficult to clean?
Not at all. The smooth stainless steel surface resists absorbing food odors and stains, unlike plastic containers that can hold onto yesterday's lunch.
Both the container and lid are designed for easy washing, and they're dishwasher safe.
Will my containers take up too much cabinet or fridge space?
That's exactly what we designed Forever Prep Box to avoid.
Its compact, rectangular shape makes it easy to stack multiple containers neatly, keeping your fridge organized and your cabinets free from bulky, mismatched storage.
How many containers should I order?
If you meal prep regularly, we recommend starting with our 6-Box Bundle, which gives you enough containers for most of your weekday meals, with a silicone sleeve for every box.
For those prepping multiple meals per day or sharing with a partner, our 12-Box Bundle offers the best value at just $16.21 per container.
What happens if my container wears out or breaks?
Every Forever Prep Box comes with our Lifetime Meals & Washes Warranty.
Your container is designed for years of repeated prepping, storing, reheating, and washing. If you encounter a covered issue, contact our support team and we'll help make it right according to the warranty terms.
What are the silicone sleeves for?
Stainless steel can become hot when reheating food. Our heat-resistant silicone sleeves provide an extra layer of grip and insulation, making hot containers easier to handle.
Every box comes with its own sleeve, so the 6-Box Bundle includes 6 and the 12-Box Bundle includes 12.
Can I put Forever Prep Box in the freezer?
Stainless steel is generally suitable for freezer storage. Leave room for food to expand as it freezes, and avoid sudden temperature changes that could damage the glass lid.
How long will my order take to arrive?
Orders are typically processed within 1–2 business days, with standard delivery taking approximately 3–7 business days within the continental US.
You'll receive tracking information by email once your order ships.
