How would I make it so a certain item is removed from an inventory?

I'm trying to make a job delivery system where the player picks up boxes and deliver them.. How do I make it so a certain item is removed from their inventory without removing all of the tools. This is what I have so far

local debounce = false

script.Parent.Touched:Connect(function(hit)
	if not debounce then
		debounce = true
		local plr = game:GetService("Players"):GetPlayerFromCharacter(hit.Parent)
		if plr then
			local holders = {plr:FindFirstChild("Backpack"), plr:FindFirstChild("StarterGear"), hit.Parent}
			game.Workspace.itemStocks.numberofSoap.Value = game.Workspace.itemStocks.numberofSoap.Value + 1
			for i,v in pairs(holders) do
				pcall(function()
					for i,v in pairs(v:GetChildren()) do
						if v:IsA("BackpackItem") then
							v:Destroy()
						end
					end
				end)
			end
		end
		wait(15)
		debounce = false
	end
end)

Thanks :)

Ok, so what your doing is destroying everything in the inventory that is a tool, but im assuming you want to destroy a specific item so heres what i would do. Im not 100% sure why your going throught every item to destroy one item but if so heres what i would do instead: Instead of seeing if it is a tool, we should check if its name is the name of the tool you want to get rid of.

local debounce = false
02	 local NameOfItemWeWantToDestroy = "Box" -- change this to the name whatever you want to destroy
03	script.Parent.Touched:Connect(function(hit)
04	    if not debounce then
05	        debounce = true
06	        local plr = game:GetService("Players"):GetPlayerFromCharacter(hit.Parent)
07	        if plr then
08	            local holders = {plr:FindFirstChild("Backpack"), plr:FindFirstChild("StarterGear"), hit.Parent}
09	            game.Workspace.itemStocks.numberofSoap.Value = game.Workspace.itemStocks.numberofSoap.Value + 1
10	            for i,v in pairs(holders) do
11	                pcall(function()
12	                    for i,v in pairs(v:GetChildren()) do
13	                        if v.Name == then -- this will check if its name is the name of the item we want to destry
14	                            v:Destroy()
15	                        end
16	                    end
17	                end)
18	            end
19	        end
20	        wait(15)
21	        debounce = false
22	    end
23	end)

Edit(I understand why your looping through all of those now, so as to delete it from the character backpack and starterpack) Ok :)
