According to the tension, the number 1745 represents the type of rubber band. Model 1745, inner diameter 17, outer diameter 45, and so on for other models. So it seems that the rubber band 1745 is still very powerful. It has many uses, and users can make full use of it without worrying about breaking it.
It can be used as a slingshot, but it should be noted that every time you use the slingshot, if the rubber band dries, you should order a drop of silicone oil, which is special for slingshots.
Drop a drop of oil on both sides first. After the slingshot is fired two or three times, the oil will be distributed in every place of the rubber band with the rubber band, so that the rubber band will feel very comfortable and the whole rubber band will feel full of power. In this way, the slingshot can be fired dozens of times with two drops of oil, which is very good, so that the rubber band will be wet and will not age ahead of time because of drying, so that the rubber band with silicone oil will be used more frequently. The above is the introduction of rubber bands.
