1/4" Pre-Finished Maple Plywood (MDF core)
Finished on ONE side
~19.125" x 11.75"
10 sheets per box
 
These sheets already have a CLEAR COAT finish on ONE side.
The Pre-finish makes these sheets great for ornaments! 
The MDF core provides stability which keeps the sheets from warping (twist, bow, cup). The MDF core also helps it cut more consistently under the laser.
