Tired of your altitude pegs coming apart when you try to move your plane around the table? I was too until I started using this always tacky Altitude Glue. Simply place a small dab on the tip of each altitude peg and let it dry. You will then be able to put the pegs together and take them apart when you want to, but they will not come apart when you don't what them to. You will have to try it to believe it!
