Magna rack is a great system for miniature storage & transport. Best to be aware the slider trays move VERY easily and don’t have a catch or method to stop them sliding all the way out – if your battlefoam bag is tilted on an angle, the trays may slide right out and fall, which wouldn’t be ideal if it happened to be full of miniatures. Keep the bag and/or tray system level and it won’t be a problem, but best to be aware so it doesn’t become an issue
