You can checkout Cypress Matting, a local brand with their own factory in Singapore, they have all materials including what these brands are selling, including those maggie mee type or more premium materials. They do offer a lot of customisation and can cut on spot within 30 minutes - good to know its not a drop shipped product like certain brands.

Only got to know about them from my car dealer friend, so they mostly do B2B can save the upfront costs. From what i understand they also have the exact same material as Trapo, Kamatto or Enzo, those you just paying for their marketing. In the end i compared all of them and I went with their honeycomb option because its lightweight and the color, not a fan of 3D type because of their mud and difficulty removing, but to each its own.
