Flat Back Crystal, SS6 Hotfix aprox 100
The possibilities are endless with these hot fix rhinestones.
They are used on everything from jewellery to clothing to nails.
These rhinestones come as hot fix versions where you can use a special tool to heat up and activate the glue at the back.
The hot fix ones are best for porous materials like fabrics and paper.
You'll have to use a good glue for attaching the non-hot fix ones to slick surfaces such as metal etc.
Hotfix means that they already have the glue built in.
Often people just use glue on with their own glue instead of using the hotfix tool.
Here is a quick video on how to use one of the hot fix tools.
Some people even add them to Henna tatoos.
