Preservation jars, 250ml, I think it's a convenient size that's a little small. I have 4 of them. I can sell them individually, but please understand that the shipping cost will be higher and it will feel more expensive. I bought a large number of jars because I make a lot of jam... but it was too many, so I'm going to sell some. Therefore, they are new. I don't know the brand name. Thank you.
