These are genuine Rainbow Loom rubber bands. Approximately 300 pieces per bag x 8 bags (4 colors) ■Condition: The manufacturing year is around 2014, so they are old. I have opened and checked similar rubber bands, and they are usable, so I am selling them. However, they are old, so please refrain from purchasing if you are concerned. The sealing part of the bags may be dusty. The rubber bands may stick together, but they can be separated. ■Shipping: Shipped via Yu-Packet Post. There is a rare possibility that the bags may tear during shipping. Thank you for your understanding.
