Here is a receiving tube for piercing needles. At times, some piercings can be hard to make, for example, the tragus piercing, in which the needle mustn't go beyond the new piercing and damage the ear. 

The tube has a 45-degree angle on one end and a flat 90-degree on the other end.

• 2g (6 mm) outer diameter and 4.7 mm inner hole
• 0g (8 mm) outer diameter and 5.8 mm inner hole
