Gardening with Mr. Pen

Tools

Having firsthand experience teaching in at-risk schools in different parts of the United States, seeing the daily struggles of students and teachers, we, a few business-minded teachers, founded Mr. Pen with a simple purpose: serving the schools in our community by providing them with high quality and affordable school supplies and tools to help them in their efforts.

Expanding our goods and services

In order to best serve our schools, we only focused on office and school supplies. Then, we decided to have products in other categories and Provide Everyday Needs.

We’re still expanding and adding new products to our catalog, but our mission statement remains the same, to provide the most affordable, high-quality products while focusing on serving our immediate community in Louisiana.

We welcome your feedback and suggestions and look forward to serving you in the future. Thank you for supporting us as we continue to grow!
