Well the quality of the product is spot on. The packaging was a little miss leading... might need a guide to order rubber bands(I guess). These rubber bands are thick and strong! You could use them as a tourniquet if you could stretch them over anything..... so....to explain better Rubber band #107 means nothing to me..... it should say in a description what you might use this for. This rubber band could be used for a replacement belt in your car.....or as a tourniquet !
