These adorable miniature glass Mason Jars are cute and colourful. Each jar measures approximately 5cm (base) by 8cm (height). They are available in four colours; Blue, Pink, Purple, Yellow.
In my own Montessori classrooms the Mini Mason Jars are used as an attractive drinking vessel for children (as shown below - complete with clean up on an accidental little spill!).
The Mini Mason Jars could also be used as part of activities designed to isolate and refine particular skills, such as transferring water (as shown below).
