Not airtight, not leak proof, and lids self destruct
I purchased these jars to store small parts & components in. Many of these components are ferrous and are coated in silicone oil to prevent flashing in storage. Tightening the lids and a quick swirl of the contents to coat them fully revealed the lids do not even remotely seal as a mess was made when the fluid sloshed out and got all over the jar.
