20 Multi-Colored 1/2" Chrome Steel Balls for GraviTrax Marble Run | Coloured Marble Set Great for Racing, Rolling | Colored Marbles Compatible with Marble Runs & Games

Description

Our 20 pack of steel marbles is designed for use with the popular GraviTrax Marble Run game. Use to replace lost colored marbles or use as extra marbles when expanding your track and racing. Set includes 20 total marbles: 5 green, 5 red, 5 blue and 5 silver. Each marble steel ball is ½” in diameter also making them the perfectly sized option to replace marbles used with many other popular games and marble runs. These steel balls will work on most marble runs and marble towers and with the solid steel construction offer a heavier weight ball than a traditional glass or plastic marble, leading to “faster” runs down the marble tower. The marble size is also great for replacing lost marbles with Gravity Maze, Brio Labyrinth and other wooden marble maze games, Brio Pinball and other pinball ball games and SpaceRail Marble Rollercoaster. Our marbles are engineered for long-lasting play and superior surface quality for optimal performance and lustrous finish. stocking stuffers; christmas gifts for teens; christmas gifts 2023; toddler christmas gifts; christmas gift tags; baby christmas gifts; christmas gift ideas; boys christmas gifts; kids christmas gifts; bulk christmas gifts; large christmas gift bags; funny christmas gifts; teen christmas gifts; christmas gifts for boys; girl christmas gifts; boy christmas gifts; christmas gifts for students; kids christmas 2023 gift ideas; christmas party favors , gravity maze replacement marbles , metal marbles , gravitrax balls , christmas marbles , 1/2 inch marbles , gravitrax extra marbles , gravitrax power , marble run marbles , gravitrax ball , gravity trax expansion sets , gravitrax replacement marbles , glass marbles , marbles for sale
