How to make a tool dev product?

Hello! So I have most of the stuff down for a dev product but how do I get who purchased it and make the tool clone into their inventory?

if receiptInfo.ProductId == productId3 then
						player.leaderstats.Cash.Value = player.leaderstats.Cash.Value +10000 --Change to Cash added when bought -- remove this
						print("Bought speed coil")
						else
