Blossom Mason and Canning Jar Storage Lid Cap, Silicone, For Standard Size Mason Jars, 3.5-Inches; Clear; 1 Lid

There are lots of mason jar caps for sale made of aluminum, plastic, and silicone. While aluminum caps are great for canning they are not as good if you are using them as everyday food storage caps. I recently cleaned up a trash can worth of rusty aluminum mason jar caps from my cupboard. They were mostly used to store homemade dog food in our freezer. I then switched to Ball brand white plastic mason jar caps. They work fine for dog food but I found them being too brittle for everyday storage caps. They break easy if dropped and I suspect they will not remain leak-proof over time. I decided to finally try the Blossom silicone cap. According to my belief silicone is a less toxic material to be in contact with food comparing to plastic and aluminum. I usually use quart size mason jars with a silicone cap to store cut pineapple, half an avocado or leftovers of mango salsa in the fridge. To my surprise the Blossom silicone cap is completely leak-proof. It fully overlaps the threading of the mason jar on the bottom to provide an extra seal. I attached pictures to show that there's no liquid escaping from a jar when it's set in the upside down position.Couple things to know before purchasing a Blossom silicone cap.Available in 3 color/types:- Clear cap without holes for storing wet or dry items- Blue cap with a straw hole in the middle for sipping and drinking- Green cap with multiple holes for flower arrangements.Available in 2 sizes:- 4 inch wide mouth- 3.5 inch regular mouth.Available in 2 quantity sets:- set of 1 cap- set of 4 caps.The only Blossom cap intended for storage is the clear cap. Blue and green caps have holes so they won't work for storage. Read description carefully and pick the right quantity of silicone caps. As most negative reviews for these caps are left by people not being able to differentiate a 1-cap set from a 4-cap set.Blossom silicone cap is very flexible and can be stored inside of a jar when not in use. It is also dishwasher safe on the top rack. I originally ordered Blossom Mason Jar Storage Lid for myself but my husband has been using this lid for his mango-pineapple chia pudding almost every day for the last three months. He brings his pudding to work and there has not been any leakage so far.Packaging indicates that the cap is designed in Alaska and made in China. Due to this and the cap being a bit pricey I give it 4 stars.Conclusion:Great leak-proof silicone mason jar cap for storing dry and liquid foods.

These are a nice idea but they do not fit all types of wide mouth jars well. I needed something leak proof for some Ball 64oz jars I use for homemade nondairy milks. My jars have a slightly sloped side at the top. My Ball quart jars have a similar design. The only jars these covers fit well were my straight-sided pint jars. I can put these on the half gallon or quart jars (which are a very standard design for wide mouth) but they do not fit snugly like the pint jars due to the shape. If your jars have any type of slope inward near the lid just be aware these will act more like a loose cover than a snug lid.

These are soft but I filled a jar up with water and turned it over and it held without leaking. These are great for re-using canning jars for general storage, packing lunches, etc. Our metal lids keep rusting because they keep ending up in the dishwasher so these will solve that problem. The pictures are a little confusing because you can click on 3 different colors, but it's not just a color option. If you buy clear you are buying a cover with no holes. The blue has a cross cut in the middle for a straw and the green daisy one is is what I would call vented or made for sprinkling.

These work SUPER well! To be clear the white ones are for sealing-only, (no straw holes in them), so perfect for storing liquids, soups, etc. One tipped over in the fridge by accident & NO leaks! I'll buy more, as they work well.

We purchased a set of these to go on some steel "Cub Cups" we bought for our kids.  Best Kid Toddler Baby Cups, Training Learner Water Cup, 18/8 Steel, 8 oz 4 Pack  These lids fit perfectly and no leaks or tears like some of the other silicone lids we purchased (the thin/stretchy kinds). I also love that these are clear /no loud crazy colors. We poked holes in the middle for bamboo straws. They work great.

I think these lids are too big. They should be an eighth of an inch smaller in diameter. Yes, they are sort of water proof, but I needed then to seal tight enough for putting jars in lunch boxes. If the lid gets slightly bumped, liquid can spill out. It's probably a fine lid for storing jars in the fridge. I returned them because they didn't meet my needs.

Only received 3 lids instead of the 4 that is stated in description. Sent an email to company yesterday afternoon (04/20/17) after I had received the order. Will update review once I hear from company. I will say these lids are awesome. They are a little hard to get on, but if you are using these to store food in and seal, you want a very tight seal. Would love to buy more but want to make sure that package and description match what I am paying for.

Works great and are pretty. The white ones don't have a hole for a straw like the blue ones. I made the mistake of not paying attention and ordering these thinking I could use a straw. I was looking at the blue ones and clicked on the white ones, my mistake. With that said, these are really cute and work well (next time I'll be getting the blue ones though, lol).
