I found that these bases are too thin for basing my 6mm miniatures on but they were perfect for doing 6mm light terrain features such as trees, fields, swamps, etc.

(Ed. Note: Customer is referring to Heavy Duty Magnet alone. Litko recommends that you adhere the magnetic base bottom to an actual base... either 0.8, 1.5 or 3mm Litko bases. Litko base bottoms are not intended to be used on their own.)
