About Castello Boxwood
Castello Boxwood (Calycophyllum multiflorum) is the modern standard for boxwood lumber in high-end model ship planking, replacing the now-scarce European boxwood. Its pale cream colour and near-invisible grain give a smooth, uniform run where no single piece stands out from the next.
Boxwood is exceptionally dense and stable, so pieces hold their dimensions precisely and bend cleanly around the hull without crushing or splitting at tight curves. The fine grain means edges stay sharp and glue joints sit tight.

Precise cuts, quality color matched wood
I’m very impressed with both the clean measured cuts and the color matching quality of the wood. Not to mention how well packaged it was to safely make its journey across the ocean. Looking forward to using the boxwood for planking and trying out the black hornbeam for some specialized work.
