Keeper Long
The elongated version of Keeper Ten: an airtight stainless steel container that's safe in the microwave, designed for pasta, sides, and long-shaped vegetables.
- Korean SUS304J1 stainless steel, microwave-safe (patented technology)
- Elongated shape: ideal for long pasta, sides, and vegetables
- 4-point airtight seal with double silicone gasket — it doesn't leak
- No abrasive coating, thanks to an electrolytic process
- Every part comes apart for easy washing
Long by nature, genuinely convenient
Some foods don't like being folded or broken. Keeper Long was made with an elongated body that effortlessly holds long pasta, asparagus, zucchini, julienned carrots, and sides that would end up crammed into a square container. The same technology as Keeper Ten, with one more shape at your service.
Pasta & spaghetti
Spaghetti, linguine, and tagliatelle stay laid flat, without breaking.
Long vegetables
Asparagus, zucchini, carrots, and green beans fit in whole.
Sides & accompaniments
Elongated sides and accompanying dishes, neat and ready.
Yes — it goes in the microwave too
Keeper Long is made of hygienic Korean stainless steel and, thanks to a patented technology, can be used in the microwave — something ordinary stainless steel can't do. Heat your leftover pasta right in the container.
- Don't put the lid in the microwave (it can warp)
- Keep heating to under 10 minutes; beyond that, the PP part may deform
- If you need longer, remove the PP part and use only the stainless container
- Avoid the microwave's oven function: the PP could melt
Note: PP (polypropylene) is heat-resistant to roughly 120–140 °C.
No abrasive coating
Most stainless containers need their abrasive coating scrubbed off before first use. Keeper Long is made with an electrolytic process: no abrasive coating, no pre-cleaning needed.
Ordinary steel
Leaves abrasive residue even after many washes.
Keeper Long
No residue: ready to use, hygienic from day one.
Shake it all you want — it won't leak
A lid with a 4-point seal and a double food-grade silicone gasket: dressed pasta and saucy sides stay safe inside. No more stains in your bag.
4-point lid
Locks on every side for an airtight seal, even on the long body.
Double gasket
Two layers of food-grade silicone against leaks from sauces and dressings.
SUS304J1 body
Hygienic steel that helps hold temperature.
Comes apart, washes clean, stays hygienic
Every part separates. The lid has a groove that makes the silicone gasket easy to remove — no limescale, no mold, even after tomato pasta.
