The JBoa's are not like most other Lasso CockRings mass produced in a factory. They are actually all hand made by Jelle the owner of Velv'Or. He cuts all silicone cords to length and strings them all before putting them in their aluminum carry along tubes.
This proces gives them all an individual look and feel. Not one is the same.
Get your JBoa at the Velv'Or shop or at one of the retailers selling them.
