These feature an 30" dragon tail made out of a material of your choice.
 
On a subjective scale of hits between different dragon tails:
Most soft leathers would rate 1~2
Stiff leathers and vegan leather are 2~3
Two-toned (double sided) or extra thick 5oz leathers are 4
Neoprene is a 6 for ultimate sting and mark
Feel free to use the notes to describe what you want so we can suggest a material.
 
Additional type customizations can increase the sting or soften the blow.
