Defender Current Comic Boards are made for collectors who take care of what’s current — from hot variants and first appearances to your weekly pull list. Each board is cut to size for Current Age comics and made from 24pt acid-free solid bleached sulfate, buffered with calcium carbonate to fight aging and deterioration. Whether you're bagging a fresh pickup or building a long box of favorites, these boards provide structure and support for the comics that define today's era.
