All the cards and envelopes are 100% recycled and printed, with vegan vegetable-based inks. The compostable sleeves are made of corn and yam, and are plastic free.
 
The makers of these fun and vibrant cards have partnered with the Eden Project, and have pledged to plant one tree for every card that is sold.
 
Each card also contains a seed token that can be planted and will grow into flowers to feed the bees, and each token contains a mix of: 

Sweet Alyssium 
Baby's Breath 
Basil 
Poppy 
Black Eyed Susan 
Marigold
