This is a set of 10 one-by-four (1x4) lumber pieces, measuring 1.9cm x 8.9cm x 60cm (19 x 89 x 600). These are leftovers from my DIY projects. The lengths may vary slightly. Some pieces may have cracks or residual sap. Please be aware of this. Shipping may take some time, so I've set the shipping time accordingly. Shipping will be done with simple packaging. Thank you for your understanding. Species: SPF (Spruce-Pine-Fir). This is a general term for evergreen conifers such as Spruce, Pine, and Fir.
