These are reproductions of the World War 1 Mosin Nagant charger clips.  They work fine, and are a lot less expensive than the original ones.  This is the second production, and these work even better than the first production.  It seems they chromed them.  Many on Ebay say they have original Finnish clips, but I have yet to see some that really are.  Originals of these type are super hard to find and will cost you quite a bit.  These work fine w/o taking a hit on your wallet.  Good luck!
