|The older MEOS had green and white tags. But I'm not sure when they changed them over to the tags like the logos on their website banner.
I don't have any organics personally, but just going by the photos ON this website for each individual diaper, looks like the organics have an earth tone tag. At least the OS does. My bamboo Sandy's have earth tone whale tags, and their not organic. So maybe the Sandy's have a different tag system or I might just be flat out wrong. Wouldn't be the first time.....
But I started out using MEOS and had both green and white tags on secondhand ones and the new geen/blue/orange combo on the new ones I had bought. But maybe all their diapers had the same colored tags initially? Do your secondhand ones still have readable silk tags in the back? They would say for sure the material the diapers are made out of.
Well, no matter what material they are, you're gonna love ME. They make awesome diapers and covers!
