These are genuine Rainbow Loom rubber bands. Approximately 600 pieces per bag x 4 bags Approximately 300 pieces per bag x 4 bags Please check the images for the colors. (The green and pink rubber bands change color in UV light) ■Condition The manufacturing year is around 2014, so they are old. I have opened and checked the same type of 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 break during shipping. Thank you for your understanding.
