Lots of socks, all the same, easy to mix and match. I have thrown away many mismatched or dirty socks and donated many that were too small, too big etc. Now these are the only socks and the only question is whether they belong to the bigger or the smaller child. Now even my 3 year old can mix and match socks and I no longer have a box of unique socks in my laundry room. I'm sure these socks aren't for everyone. They shrink a bit with washing and may not last until children hit the upper end of the age range. They're also lightweight - fine for the climate I live in, but maybe not for you. But they are of great value and WILL CHANGE LAUNDRY FOREVER.
