Instruction
1.Since the rubber material is soft and elastic, we recommend choosing a rubber pipe cap, that is slightly smaller than the outer diameter of the product to be protected. For example: if the outer diameter of your product is 5mm/0.19in, choose a 4.5mm/0.17in rubber sleeve!
2. 9-13 mm end caps can be used for billiard cues.

Note:
Choose the length of the rubber sleeve, for example: the actual size of the rubber sleeve = the length of the rubber sleeve L-2mm/0.08in, i.e. 15mm/0.59in long rubber sleeve, the exact length of the sleeve is about 13mm/0.51in.
