These rubber bands are perfect for everyday use at home or in the office. They hold files together or blueprints mail or small packages. They have good spring action and don't get dry rotted as quickly as other rubber bands tend to. The only downside is that they do get a little weak over time and you have to replace them if something needs to be held together for a long period of time. But I would rather them get weak and lose their elasticity than get dry and snap! They are economically priced and therefore are a good value!
Has the kind of elasticity you look for in this type of product. Seems to be more durable than many others I have used. Great for the hobbyist who needs to bundle wires for storage after initial use of the wire needed. Works well on pulleys and wheels.
