How wide is the 308?

The 308 is 2 1/16" (2.0625 in.) wide.

How thick is the 308?

The 308 is 0.09375 inches thick.

Is the 308 flexible?

The 308 is rigid with negligible flexibility.

Is this accurate enough for me?

The 308 printed scale is accurate to 0.7mm/m. It is suited for construction, carpentry, and home improvement. If you require high-end accuracy for furniture making or metal working, we recommend investing in a ruler with tighter tolerances.

How do I care for my ruler?

If dirty, wipe down with a damp cloth. Use only water. Solvents can dissolve printed markings.

    Packing not great, ruler as expected
    It’s a ruler, so it’s the edge that matters. If you are obsessive about details then maybe you’d return it due to the scratch. ¯\_(ツ)_/¯ … I’m not, an inexpensive ruler that will do what I bought it for. Comes in a long box with paper stuffed inside. There was a small hole in the box that indicates the scratch was not there when it was shipped.
