Testimonial Section

"I've been ordering menthol crystals in bulk (55 lb) from USPMENTHOLCRYSTALS.COM for my lab and business for about a year now. We've looked at other sellers out there and none of them are better in price and customer service. Quality of menthol crystals are excellent! Thanks for valuing us as a customer!"
