Are coverplates of Hohner crossovers attracted to magnets?

Hi David,

I play guitar and harmonica in a rack. I've ordered a new rack that uses magnets to hold the harmonica in place as opposed to the more traditional style of rack. My Seydel and Lee Oskar harmonicas have cover plates that stick to magnets. I'm interested in trying out a Hohner Crossover. I don't live near a shop that sells Hohner crossovers. Could you see if a fridge magnet sticks to the cover plates of your Hohner crossovers? I've heard that some cover plate materials don't stick to magnets.

It's a bit of an odd question I know, but I would like to hear your answer before I order a Crossover.

Thanks and enjoy your day,

Greg
