We are the very manufacturer and patent holder of Nap zapper in China. This is searching for the distributors, importers and agents for selling our Welkin Nap zapper(unti-drowsy alarm). 1. The innovative and our patent product is designed to lie on one's ear when driving or head-nodding conditions. It works on the principle of electronic balance. When working, a pleasant awakening sound alerts you when the head nods forward that you should not during the highly wholehearted-needed situation. Wow, so great!! That would be sound reasonable and would diminish the car accidents and protect ourselves. 2. Here I could forward to you our official FCO with the maturity of 2 months later on the very product. Discount of 1~10% could be given according to the amount of your quantities and your sincerity. More technical spec. No Pack: $1.88 500minimum Blister Pack $2.15 500minimum Leather Box Pack $2.54 500minimum 3. All the samples should be paid in two ways: one is the T/T to our account; another is contacting your local DHL instead of you to collect samples from us. And only the credible partner could enjoy free charge of samples. Finally I want to say if you have chosen Welkin, you would have chosen the lowest cost and a trusted partner, finally you would have chosen a win-win strategy.
