Every millimeter of the TierPod 3 is built to eliminate soggy sides, leaking zippers, and wide cafeteria-tray bulk.
Pack a full workday of fuel without compromise: one deep 600ml base bowl for hearty mains plus two 400ml upper bowls for crisp greens, berries, or yogurt.
Dual semicircular handles sit completely flush while stacked, then flip upright so you lift each packed bowl effortlessly out of the vertical sleeve.
Precision grey silicone perimeter gaskets and a press-down center vacuum button lock in thin dressings on the train, then pop open to vent microwave steam.
Tailored cream woven fabric with espresso-brown piping, 3-layer thermal foil insulation, dual silver zipper pulls, and a comfortable arched top carry strap.
No more microwaving your fruit alongside your pasta. Three independent round matte cream bowls keep temperatures, textures, and sauces completely isolated until noon.
Snap on the interchangeable grey-rimmed lid and press the center silicone button flat for an airtight commute seal. At lunch, pop the center vent open for splatter-free microwave heating.
Unzip the dual silver pulls and use the flipped-up lid handles to draw each bowl vertically out of the insulated sleeve—leaving your desk clean, organized, and clutter-free.

Architectural Commuter Design: Finished in warm matte cream with dove-grey accents, espresso-brown contrast piping, and polished silver hardware, the TierPod 3 looks like a tailored travel case on conference tables and breakroom counters.
Selective Microwave Convenience: Unlike heavy stainless jars that trap you with lukewarm soup or single-tray bento boxes that heat everything together, each BPA-free food-grade PP bowl heats independently in 90 seconds.
Effortless Nightly Reset: All three round grey lids are 100% interchangeable across every bowl—ending the nightly hunt for matching Tupperware lids—and clean up easily on the top rack of your dishwasher.

Heat only your deep 600ml entree bowl while your dressed arugula and afternoon yogurt stay crisp and cool on your desk.
Its 5.7-inch (14.5 cm) round base takes up half the horizontal bag floor of flat bento trays—zero sideways wedging required.
Smooth rounded matte cream interiors have zero sharp rectangular corners where sauces hide, rinsing clean in seconds.

Load your main course in the deep 600ml base bowl and snacks in the two 400ml bowls, snap on the grey rims, and press the center vents flat.
Lower all three bowls by their fold-up handles into the cream woven thermal sleeve and draw the dual silver zipper pulls shut with zero bulge.
Carry comfortably by the arched woven top strap or stand it upright in your backpack—then pop just your hot bowl in the office microwave at noon.
I love this stackable set! The bottom bowl has plenty of room for my main dish, and I use the two upper bowls to keep my sides and snacks separate.
The lunchbox is very sturdy and well made. The three containers are a good size and fit perfectly inside the bag. They keep my different foods separate without leaking, and the whole set is lightweight and easy to carry.
All three containers slide right into the tall bag, and the two zipper pulls close smoothly without me forcing them. The cream and brown look is so pretty too. I've gotten several compliments at work!
I can pack my lunch and snacks in the three bowls without taking up a ton of room in my work bag. The matte cream and brown trim are really pretty, too.
My favorite part is the fold-flat handle on each lid. It's so much easier to lift a bowl out of the bag, and the handles tuck away neatly when I stack everything.
The three round containers feel durable and are easy to clean. They keep my foods separate, and the tight gray rims have prevented spills when I take lunch on the go.
I love my three-tier lunch set, and my nieces and nephews have sets too. My sister loves how easily they wash up. They're durable, and we can pack all sorts of different meals in them.
The bowls have kept my food fresh and haven't leaked in my bag. The vent buttons are handy, and the fold-flat lid handles make the bowls easy to lift out. Cleanup is simple too.
I usually slip the tall bag into the side of my backpack for work. When I'm carrying it by itself, the woven handle on top is comfortable and feels sturdy.
I pack my main meal in the deeper bottom bowl and use the other two for yogurt and snacks. The stack fits the bag nicely, so it zips up without bulging out.

Yes. All three inner bowls are crafted from BPA-free, food-grade microwave-safe PP (rated up to 248°F / 120°C for up to 3 minutes). Simply pop open the grey central silicone air-vent button on the lid—or remove the lid—before heating so steam vents cleanly.
Yes. All three matte cream bowls and their grey silicone-rimmed lids wash cleanly on the top rack of your dishwasher. For the outer cream woven thermal carrier bag, simply wipe the interior foil liner and exterior fabric clean with a damp cloth.
Every single lid features dual recessed semicircular handles that fold completely flat when stacked and flip upright when you unzip the bag. You just grab the handle loops from above and lift each bowl straight out like a bucket—no tipping or fingernail prying required.
No, and that is what makes meal prep so practical. The bottom container is deeper (600ml / 20.3 oz) to hold a generous main course like pasta, grain bowls, or entree salads, while the two upper containers hold 400ml (13.5 oz) each for fruit, Greek yogurt, soup, or sides—giving you 1,400ml (47.3 oz) total.
When the grey perimeter rim is snapped down all the way around and the central silicone vacuum-release vent button is pressed flush, each bowl forms a 360-degree leakproof seal that passed our 30-minute horizontal shaker test with zero drops spilled.
Not at all. The cylindrical woven carrier bag is tailored specifically around the 3-bowl tower with extra vertical headspace and dual polished silver zipper pulls, so it zips shut smoothly with zero bulging.
