3 mm ( 1/8") Boxwood Single Sheave - High quality premium rigging blocks ( 25/bag)

Thumbs up!

Looking much better than the square shaped blocks provided in the majority of kits. Not just the 3mm blocks, but the whole range from Dry-Dock Models makes your model stand out.

I am very happy with them. In fact I plan to replace ALL the blocks from my present project with blocks from here. These are tiny (3mm) and still I was able to pull a thread through them without sight magnification or wire loop threaders. Holes are that clean!
