This piece is crafted from natural solid wood. Color and texture in wood will vary and natural holes and subtle openings add unique character to your piece. Wood "breathes" and it is normal for cracks to present themselves over time. This is NOT considered a defect. Please note that measurements are based on the straight sides of the square. When placing a round glass on a square table, you must account for the diagonal measurement which will be longer. If you have any questions regarding glass size please contact our team.
