NSG Rapide magazine, used, hold around 20 rds

Stock / factory National Survival Games Rapide magazine. Fits the standard Rapide slide connecting piece. 
These are factory magazines and are mostly in good but used shape. They hold about 20 paintballs total. 4 tubes of 5 balls. Condition varies but all are crack free that I can see. 
Some have the splat icon on the end and others are blanks.
