Rubber Bands Maintenance Tips
The rubber band is a kind of polymer compound with complex composition. Things like this will continue to oxidize when exposed to air, sunlight, and other environments, so we should try to use them in a low temperature and dark environment.
In addition, the flexibility of the rubber band has a certain range, and frequent overstretching will reduce its lifespan, so when using the rubber band, be careful to avoid overstretching.
