What's the point with laundry nets?

I've seen laundry nets mostly in movies growing up. As they were not common in my household and as me, you might have been wondering about what's the point
What are Laundry nets
Laundry nets, also know as washing machine net, are mesh nets made commonly of durable polyester mesh material. This is to allow for water and soap easily pass through the netDifferent types of Laundry nets
You can find laundry nets in a wide selection of colors and sizes, but white is the most commonly color found. Material can vary, but it's always a mesh style bag and with a closing mechanism. I see zip bags most these days, but you can also find other types, such as drawstrings bagsWhen to use Laundry nets

With using a laundry net, you won't have the issue that the washing maching eat some of your clothes. As they'll be safe inside the net, during the wash
Laundry net is also perfect on bigger items. I've started using them on some curtains, to prevent the curtains rings falling out and when washing the inside of motorcycle helmets
You can also use the laundry nets the other way around, by putting something that can easily damage other clothes inside the laundry net. A good example would be something with velcro. It have happened quite a few times I've washed something with velcro, then velcro have grabbed threads or decoration on other clothes, pulling it off. Putting the velcro item inside a laundry bag, minimises the risk for this happening
Some also use laundry nets, to separate differing peoples clothes. So each person use their own laundry net, then all go into the same washing machine. So you can save on the number of washes you need to take, but also can easily separate different peoples clothes
