I purchased a large quantity of these miniature items to remove the keyrings and display them. I believe they are made of metal, not plastic. The back of the bag has a see-through pattern. They do not open or close. They have not been used. Overall, the C-links on the chain are not neatly aligned. Bag dimensions: Approximately 4.3cm wide x 5cm high (from handle to bottom) The bag shape appears to be slanted, not perfectly vertical. Marking: Decoration Weight per piece: Approximately 48g They have some weight to them. Total length: Approximately 12.3cm Different colors are also available. What do you think? Thank you. ※ I have pets. ※ I am a smoker. Please do not purchase if you are concerned about this.
