I collect National Treasures booklet cards — will these 187mm holders fit them?
Yes, these horizontal booklet magnetic holders are sized at 187mm specifically for booklet style cards including National Treasures and Playbook, which are too wide for standard holders.
Is the magnetic closure strong enough to hold if the holder is displayed upright?
The magnetic closure holds firmly in upright display. Place the holder on a stable, level shelf and avoid stacking heavy items on top so the seal is not stressed.
Will the acrylic yellow or cloud over time when displayed?
The acrylic is made for long term display of valuable cards. Keep holders out of direct sunlight, which is the main cause of yellowing and fading in any acrylic display case.
Can I fit a booklet card that is already in a penny sleeve inside this holder?
The 187mm holder is sized for the booklet card itself. A thin penny sleeve generally still fits, but check the closure seats fully before displaying so the magnets stay flush.
Does the 5 pack come with protective film I need to remove before use?
Acrylic holders ship with protective film on both faces. Peel the film off all surfaces before inserting a card, otherwise the display looks cloudy and dull.
