Hi I'm Lena, CEO of Eco Peaceful, LLC. I am a passionate vegan environmentalist who believes that manufacturers should be responsible to produce quality products that last a very long time & package their products in an eco-friendly manner so wild animals can live their lives in their natural environment After watching Plastic Planet and other documentaries I was so shocked what plastic does to the animals and humans, so I decided to change my lifestyle: I started to grow my food to reduce plastic consumption and started my zero-waste business in 2012 to manufacture organic, natural and non-toxic products that are packaged plastic-free and in the most Eco-friendly way possible. If you make your own food & drinks (tea/coffee, smoothies...) then mason jars are an important part of your daily life. What you may not know is that the common canning metal lids have a PVC/vinyl coating with a plastisol/PVC seal gasket. That has always bothered me since the liquid in the jar vapors and drops back down into my drink or food. I became especially concerned when I saw that the vinyl coating was flaking off just from putting vinegar in a glass jar (it was not even touching the coated metal lid). I was inspired to look for alternative lid solutions. Plastic caps lids are also not a good option since the plastic degrade and shed microplastics & release toxic chemicals; BPA-free is rarely truly BPA-free and/or replaced with worse chemical(s). Plastic lids are breakable, heat-sensitive (can't be boil to sanitize); and the most important for me - pollutes the environment and harms/kills wildlife. Using stainless steel lids with a silicone gasket also gives me peace-of-mind since they are built to last 'forever', so no need to be wasteful by constantly throwing away and buying metal or plastic lids.12 WIDE MOUTH 316 STAINLESS STEEL LIDS & 12 SILICONE GASKETS (TOTAL 24 PIECES). Fits wide mouth Kerr / Ball Mason jars with 3 3⁄8" outer diameter of glass jars.FITS ALL WIDE MOUTH MASON JARS BALL, KERR: from half pint (8 oz) to half gallon (64 oz). LIQUID & DRY STORAGE: airtight leak-proof silicone seal. Not for CANNING!HIGHEST FOOD GRADE MATERIALS: 316 SURGICAL STAINLESS STEEL LID - 316 Stainless Steel is used in biomedical applications & has the best rust-proof properties, moisture tolerance, strength & food safety. 100% GENUINE SILICONE - NO FILLERS - NO WHITE WHEN PINCHED: If silicone turns white when pinched or stretched, it indicates low-quality silicone or added plastic fillers. We are paying extra for the best silicone for durability & food safety.WHY USE 316 SURGICAL STAINLESS STEEL, NOT PLASTIC OR ORIGINAL CANNING LIDS? Even though the lid is on top, liquid vapors collect & drop back down. Canning lids rust, has PVC/vinyl (worst type of plastic) coating and seal. Studies show most "BPA-free" plastic is NOT BPA-free and/or replaced with worse chemicals. Plastic sheds micro-plastics & leaches harmful chemicals, pollutes environment & harms/kills wildlife. 316 SS lids with silicone seal are safest option for health & environment.DISHWASHER-SAFE, OVEN SAFE, FREEZER SAFE: Temperature Range -40F - 425FPHTHALATES-FREE, BPA-FREE, PVC-FREE, PLASTIC-FREE.
