2 pack Weck 743 mold jars!!
I LOVEEEE my Weck jars, perfect for sourdough started. The lid quality is really good haven’t had any issues with them and it seems to be leak proof. It is dishwasher safe and is very easy to clean. Fits a lot of stuff in it, it is fairly roomy for whatever you’re needing it for! I also like the overall look of them. I would say if you need a good jar to store anything but the Weck jars. I am planning to get more due to how much I love them! You can stack them but I keep my lid loose so I don’t think you should unless your lid is fit tightly. if you’re thinking about it, just buy them!!

Great glass jars for canning and beyond!
I absolutely love weck jars. They work great for canning but I like to use them for large smoothies or coffee drinks.

Very good product.
I wanted something smaller for my sourdough starter, but hey. These work just fine! The straight sides make it easy to scrape down, the clips hold the lid on nice and tight. I like them!

Perfect for My Sourdough Starter
These Weck jars are absolutely perfect for sourdough. The wide mouth makes it super easy to feed and stir my starter without making a mess, and the glass is thick and durable. I love that they don’t have any metal parts touching the starter—just glass and rubber—so there’s no risk of corrosion or weird smells. The glass lids also sit loosely on top, which is great for letting the starter breathe without drying out. They look beautiful on the counter too, which is a bonus! If you bake sourdough or keep a starter going year-round, these jars are worth every penny. Functional, clean, and so much prettier than a random mason jar!

Great for sourdough!
I use this for my sourdough starter and it’s perfect! Seals tight when you need to store but sits nice when you are feeding! Perfect size!

Great Sourdough Starter Jars
These jars are just the right size to grow your sourdough starter. They're just deep enough with a wide mouth, making for easy cleaning. The lid comes with clamps and rubber rings which are easily removed leaving a lid which can be loosely placed on the jar.

Perfect for Sourdough Starter
Absolutely perfect! I am starting my sourdough bread adventure and after watching many videos, this was the most recommended jar. I am very glad that I purchased two, works perfect for transferring a small amount of the starter to a new jar and being able to discard the rest. Clean the first jar and it's ready for the next day's feeding. The glass is nice and thick, I am not worried about dropping it in the sink during cleaning. And since the starter needs air, I use it without the rubber circular band.
