I purchased a large quantity of these miniature items to remove the keyrings and use them for display. 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 connected. Bag size: Approximately 4.5cm wide (max) x approximately 4.3cm high (from handle to bottom) Mark: Decoration Weight of one piece: Approximately 40g They have some weight to them. Total length: Approximately 10.3cm Different colors are also available. How about it? Thank you. ※I have pets. ※I am a smoker. Please refrain from purchasing if you are concerned about this.
