This is a mini jar. I've never seen one like it before. It has an anchor mark and is very cute, so I'm offering it for sale. The inside of the jar is smooth and clean. What you use it for is up to your imagination! How about making pudding and using a milk bottle lid, tying it with string for a stylish look? Mini jars are rare, so whatever you put in them, it'll be super cool and cute depending on your ideas. The material is pottery!?, similar to teaware♪ Size: Height 5cm, Mouth width 4cm - Quantity: Set of 4 - Design: Jar-shaped - Color: Brown - Features: Anchor pattern Thank you for looking!
