Acrylic chain parts. These are imported products. When 10 pieces are connected, they are about 8 centimeters long. Blue系 (blue-toned), the base is transparent. 27g or more, approximately 180 pieces based on gram calculation. Please check the photos for the size, etc. I am organizing materials for my personal hobby. I inspect them, but my eyesight isn't very good, so I may miss something. Also, there may be lint, dust, and fold marks. For those who understand that these are items stored at a private residence by an amateur. Please refrain from purchasing if you are concerned about minor details. Please check my profile for combined shipping information.
