Visit: https://www.facebook.com/HobbyworldshopThey are ok, but actually they are 15mm not 12.8mm, so be aware when you order them for your project.
in my case they are now laying on a shelf... as sending them back is a waste of money.
HK please update them!!The tubing is not actually .5 inches, more like 5/8th. I can fit a .5 in square wooden dowel, INSIDE this tube.
The paint is very good, scratch resistant and evenly applied. The tubing is also nice and straight.
