You may request free tracts from the Fellowship Tract League. Their tracts are single fold tracts. They have a two color cover. The text is black on white paper. Please be sure and include what language or languages you are interested in. Please include your correct mailing address. You may see Fellowship Tract League's web site at www.fellowshiptractleague.org
The Fellowship Tract League is located in the USA. They have tracts in around 77 languages. If you send an offering, you will get the tracts quicker. If you don't send an offering, you will need to wait until the Fellowship Tract League receives a gift to pay for expenses of printing and shipping the tracts. Since they receive many requests for tracts, it will probably take some months or maybe over a year.
