Stainless Steel
Our 18/8 stainless steel containers are crafted from the highest-quality, food-grade steel that’s built to last a lifetime. This material is naturally free from BPA, BPS, lead, and other toxins commonly found in plastic, ensuring your food stays pure and safe.
The “18/8” refers to its composition, 18% chromium and 8% nickel, which gives it superior resistance to rust, corrosion, and staining. Unlike plastic containers that can warp, retain odors, or break down over time, stainless steel remains strong, clean, and endlessly reusable.
PLATINUM SILICONE
Our silicone products are made with platinum-grade silicone are designed for a safer, more sustainable alternative to plastic. Platinum silicone is a high-quality, food-safe material made primarily from sand (silica) and oxygen, without fillers, BPA, BPS, phthalates, or other harmful chemicals found in many plastics. Our silicone products meet FDA standards, as well as strict European LFGB standards prohibiting fillers.
It’s durable, flexible, and long-lasting, making it ideal for food storage and everyday use. Unlike plastic, silicone won’t crack, leach, or degrade over time, even when exposed to heat or freezing temperatures.
Product Materials & Care
Stainless Steel Containers
Stainless Steel Containers
Stainless Steel Containers are made from 18/8 stainless steel. Silicone lids are made from platinum-grade, food-grade silicone that pass strict EU LFGB standards. All are dishwasher safe, top rack recommended. Containers and lids are freezer safe.
Containers are oven safe up to 300º F. Containers can be used at higher temperatures or under the broiler (without the silicone cover), but above 450º F the steel may discolor. Discoloration does not affect performance. Do not use above 600º F.
Insulated Food Jars
Insulated Food Jars
Insulated Containers are made from 18/8 stainless steel. 12oz and 18oz Food Jars have an all-stainless interior, and the lid has a silicone seal. Older versions have PP#5 inside plastic rim (that does not come in contact with food).
They are dishwasher safe, top rack.
Plastic lids are dishwasher safe but research has shown that it is best to keep plastics out of high temperature environments.
Our Insulated Jars are designed to keep the temperature you start with, so pre-heat by pouring hot water inside and letting sit for a few minutes before pouring out and adding your piping hot food, and pre-chill in the freezer for a few minutes (lid off) before adding your cold food.
