10pcs 9mm snooker tips.

The ferrule is the connection between the leather tip and cue. It is to protect the wooden part of the cue and to connect the tip to the cue as a whole.

The tip of a snooker cue stick (often just called a "cue tip") is a small, crucial component located at the very end of the cue. 

  Here's a detailed description:

Material:
Traditionally made of leather, specifically compressed and treated pig or cowhide. Some modern tips may use synthetic materials or layered leather for consistency.

Size:
The diameter of a snooker cue tip typically ranges from 9mm to 13mm, to allow for greater precision and control in striking the smaller snooker balls.

Shape:
The tip is usually shaped into a dome or slightly rounded profile (called the "radius" of the tip), which affects how much spin or "English" can be applied to the cue ball.

Hardness:
Cue tips come in varying degrees of hardness — from soft to hard.

Soft tips provide better grip on the cue ball and are preferred for applying spin.

Hard tips are more durable and provide a crisp hit but less grip.
Snooker players often prefer medium to soft tips for better cue ball control.

Attachment:
The tip is glued to a ferrule, a small protective cap (usually made of brass or other metals) at the end of the cue shaft, which helps prevent the wood from splitting.

Maintenance:
Cue tips require regular shaping, scuffing, and chalking to maintain optimal performance. A well-maintained tip allows for accurate shots and proper contact with the cue ball.
