How can I save a player's in-game earned gear?

In my game, players can use in-game currency to purchase fun gears. I would like to know how I can save a player's in-game gear when they leave and join the game.

Thank you!

Hai cyclox You can change Tool to anything but you also gotta change in Loading sequence

Saving Below

	if game.Players.LocalPlayer:WaitForDataReady() then
	player = game.Players.LocalPlayer
	player:WaitForChild("Backpack")
	player:SaveInstance("Tool", player:FindFirstChild("Backpack"):FindFirstChild("ToolName"))
	end

Loading Below

game.Players.PlayerAdded:connect(function(player)
    if player:WaitForDataReady() then -- Wait for the player's data cache to load or skip if it doesn't
        print(player:LoadInstance("Tool"))
    end
end)

IMPORTANT: You will have to add the Save feature to activate when the player bought the item
