Right! I made 50, yes 50 soap savers from an icing gun kind of bodged onto a silicone extruder called the ROUGHNECK haha! I was bloody lovin' it in my wee zone going squeeze squeeze squeeze. 
 
They come with a soap and are a tenner, they do work, people have told me! Keeps ur soap dry makes it last for longer.
 
So, I have put a few options in the variants but basically they are all totally different but I'll choose u a good one. If u trust me!
