These fabulous translucent - slightly see through - are one of my faves, the colours are so bright and the effect the light has on them when worn is beautiful.
There are four styles left the u shapes, the hoops with green top, the hoops with spotty top and the triple drop. The tripe drop is approx 5-5.5cm in length and the others are approx 3-4cms in length.
The ear posts are all surgical steels, you shouldn't have any allergy issues with them.
