With every order you make from our web site, you help us plant a tree!

We decided to partner with ECOLOGI as a way for us to play a role in helping to revive and restore our planet. Through projects supporting tree planting to community restoration, each purchase you make on line from Mari Thomas sends a percentage of the sale automatically and directly to these projects.  

Ecologi are aligned with our values and are a fantastic gold standard, B - Corp organisation who are authentic and transparent – with their range of projects supported through their organisation being easily accessible.
