The special design of DEAR DEER plastic multi-blade plug is there are some blades around the plug that keep it tightly inserted, not come off. The plug block on top of pipe can prevent rain drop in and the plug block at bottom can prevent soil pushed in. Those protect the inside of iron pipe not to get rusty.
