Why does the ERGOSLIM has a different tube?

The ERGOSLIM chastity belt.

We decided to invent a new tube for the front shield of the ERGOSLIM model, which looks like a „C“. This form takes a lot of pressure from your testicales. You can put your testicales in the further eroded tube, this offers the wearer great advantages. The tube is slightly slimer as the maximum width of the front shield.This chastity belt is especially made for wearer with sensitive or big testicales. You can also get this tube with the BASIC model, just let us know in advance.
