here is another product soon to be available for those that want it, button guards - a  bit big and not a mod I would go for but some people might like them - personal taste thing

"(THIS IS THE PROTOTYPE) Just doing some test fits, they fit with no issues. These will go to powder coat in the morning, finished in black same as Stern powder $52 shipped in the USA. Plain stainless $40 so you can trick them yourself. If you want them shipped to your choice of powder coater this isn't a problem. Send payment to pinprotection@gmail.com please add a note Metallica flipper button. Thanks MP"
