I know the basics of Datastores but i do not know how to save objects...This script is suppose to make a folder in the player, and if there are any Tools/Bricks/Models/etc...inside of that folder then insert them into a table and save them to the datastore. It does not work though so what i can i do to store and load them?

local DataStore = game:GetService("DataStoreService"):GetDataStore("BackPack")
game.Players.PlayerAdded:connect(function(player)

local Storage = Instance.new("Folder",player)

Storage.Name = "Storage" --Name of folder

local key = "user-" .. player.userId --Key
local storeditems = DataStore:GetAsync(key)

if storeditems then
    storeditems.Parent = Storage
    else
        local items = {} --Items table

        local get = Storage:GetChildren()-- get items
        for i, v in pairs(get) do --save tools
        table.insert(key, v)
        DataStore:SetAsync(key, items)


        end
    end
end)


game.Players.PlayerRemoving:connect(function(player)
    local items = {}
    local key = "user-" .. player.userId

    for i, v in pairs(get) do --Save tools
    table.insert(key, v)

    DataStore:SetAsync(key, items)

    end
end)
