“As a soap maker, I couldn’t be happier with SPI soap boxes. They give my products a clean, minimalist look, which me and my customers love. Plus, knowing they’re made from recycled cardboard aligns perfectly with my mission to create eco-friendly, sustainable products. It’s a win for my business and the environment. I highly recommend them!”
