Surgical Steel Marble Effect Tongue Bar.
The bar is 1.6mm in thickness; this is standard for a tongue bar. The length can vary from 12mm to 18mm. The average is 14mm although this can depend on the individual. 
Returns are not accepted on any body jewellery. Please Ensure you order the correct size.
Both balls come off the bar, therefore if you currently own a bar that is the correct size for your piercing you can interchange the balls.
