* Improved coil memory.
*Retract faster and better minimal sag.
*Resistant to kinks.
*Longer service life,resistant to pressure.
*Working length is approximately 60% of the the coil’s length.
Custom of orders coils with other sizes,colors,tail lengths,retracted lengths,coil diameters and retracted length are welcome!
1,A coil’s retract ability is affected by coil’s wall thickness and the mass weight.
2,Excellent retract ability is affected by the small diameter.
3,The big diameter coil could be easy to stretch and used comfortably.
4,If you want a stronger elasticity,let one tail go through the middle of coil,pull it out at another end of coil.(The coil’s length of working could be shorter.)
