   I am a big-order buyer, can you send samples to me before I make a big order? 

   Sorry that we cannot send out free samples but blank sample We are very serious about the quality of the products we sell and we guarantee it by offering a no-satisfaction return and exchange policy We have many customers who are ordering at 50 and above quantities daily
