These are fantastic additions to anyone's pin collection. They close with a push mechanism, removing the need to carry Allen keys and even when unlocked they take a lot of effort to remove.
I bookmarked these because MTG has recently been giving away top 8 pins that pinfinity makes and I have friends that regularly lose pin backings. These came in clutch and we're delivered in a couple of days and we're perfect. Affordable, fast delivery, and same quality as the originals ^^ highly recommend.
