Unfortunately, Both large and small building slip from Hobbyzone is out of stock. (I got a back-ordered mail from the shop.) Instead of it, I found an another building slip by Ukraine company.

(LMG BB-09 Sailboat building berth)

 

It covers hull up to 750mm, and has a rotation function like the big size building slip. It has higher price ($100) and exterior is not durable more than the Hobbyzone made. (Thinner wood panel with relatively inaccurate laser cutting.) I ordered one because I was curious about the contents and its structure.

 

They are also selling similar berth for plastic airplanes and battle ship models. Most of them look not that useful, but their challenges are interesting.
