I've owned several panties another company which had considerably more expensive, yet the closure ever broke or he opened himself.
The panties of Europet sit not only better, but the closure is also better at worlds.
It is stable, does not open by itself and also does not interfere.
As a contribution I do not use the supplied binding, but affordable sanitary pads from the drugstore.
In addition, my dog can brush with the panties also still itself.
It's all nothing more accidentally wrong.
Nice not having to having trouble with cheap panties again at the next heat.
