The perfect pair of medium hoops, these square sleepers are made of gold plated sterling silver and have a diameter of 25mm. Being 1mm thick, this means they are on the daintier size so they are ideal if you are wanting to go for a slimline, rather than chunky pair. They weigh 1.4g so are super lightweight and have sleeper style fastenings which means they are suitable and comfortable to wear at night.
