These are great Russian Makarov magazine projects that will work great in your Makarov pistol with a little work. These magazines have external pitting that will need cleaned before use.  These should be disassembled and cleaned thoroughly before trying to use them.  Most of these are Russian, but there are probably a few Bulgarian magazines as well.  Some are serial numbered on the spine. This sale is for ONE magazine although a few are pictured to show condition.
