Quoted from protectors:
Mirco Steffen from highclasspinballs aka https://mircoplayfields.com/ aka jjp supplier aka ... is not associated at all with Mirco from playfield protectors... Same given name - that's it.
But - of course it makes sense to protect all playfield with our playfield protectors... that includes playfields from the other Mirco
All the best
And let me vouch for their products and staff, both are awesome. If anyone is thinking about adding a layer of protection to a playfield, these fit like a glove and do a wonderful job.
