You could always check Bricklink. The mask is only about £4 and the horns + hand are even less than that.
ok @Monopoly so I did they math and it would be $13 to replace the parts. but is that really worth it on a $4 figure?
By my calculations, the missing pieces could be purchased for 2 dollars and a few cents, not including shipping costs
Also as far as I can tell, the Mask Maker & Skull Grinder set sells for $40-60, so I think you’re undervaluing Kulta a bit
G2 sets are crazy expensive.
This kinda depends on if you’re keeping him or selling him. If the cost of completing a figure is more than the profit you’d make in the sale, then no it really isn’t worth it. If you want your set to be completed for your personal collection, then I’d say it is worth it - resale price is only a relevant figure if it’s up for sale.
it hurts my soul
