Oak window board

Great quality, flat & straight. Packaging damaged but fortunately did not affect boards. Recommended.

Thanks for the review Mike. This is precisely why we take the time to package as best as possible, as there are unfortunately times when couriers are a bit 'heavy handed' with parcels. The good news is that the protective packaging does the job and the contents are as they should be!
