What is the advantage of using aluminum or copper ?3. Why are copper rings longer than aluminum rings ?4. Why do you use silicone inside ? Does it not slide out easier with the silicone ?5. Do you have the physical dimensions of each ring on a list ? I wouldlike to know diameter (outside and inside) and length.6. Are the rings available in any color ? Can you make a custom color ring if I requested it (with large quantity) ?7. Can you give me prices ?8 Can you package them with our name on the package ?9. What type of packagings are available ?10. Why do some rings have a screw inside ? Does this screw break the hair sometimes ?Thanks for your quick response. **** Hidden Message ***** Co:Cinderella 100% Human Hair Extensions Add:12304 McCann Drive Santa Fe Springs, CA 90670, USA Tel:(800) 332-9246 Fax:(562) 903-1064 Email:info@cinderellahair.com Website:www.cinderellahair.com Contact Person:antase Country:USA **** Hidden Message ***** info@cinderellahair.com
