eco eggs are made in the USA from corn starch, 100% renewable content, and are fully compostable after use. They are made from non-toxic, durable plastic and have a tight snapping closure. eco eggs are extra-large in size measuring 3" x 2.25" so most bagged candies fit inside. They come in 5 assorted colors: pink, yellow, green, blue, and purple. eco eggs can be stored and reused for many Easters. After use, dispose of eggs in industrial compost.
