Disappointed
Nothing exceptional about the taste; loaded with salt like many others in your local store, and not packaged to restore freshness. Maybe because it's a small box the seller assumes it will be used up within a week🤷

TOO SMALL
Size: Medium, Color: Blue
Nice socks, but they are way too small. Says they fit size 6 - 10. I kept 3 ( I wear size 8) and gave 3 to my daughter (size 8.5). We both agreed that they were just too small.
