Purchasing personal items to sell through LLC

I have a small business (LLC) where I am able to sell used (and new) items.  I have some relevant stuff I own personally that I'd like to sell through the business.  Can I pay myself through the company checking account (I would write a biz check) for the items?  (I would pay myself a reasonable amount that allows for profit on the business side, so no funny business.)

 

If so, would the amount I pay for the items (to myself) be an expense/cost for tax purposes?
