These are genuine Rainbow Loom rubber bands. Mixed colors, approximately 600 pieces per bag x 5 bags Regarding 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 listing 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. Regarding shipping: They will be shipped via Yu-Packet Post. There is a rare possibility that the bags may break during shipping. Thank you for your understanding.
