1/2インチ リップ付きセミリジッド ハイカードホルダー（200枚入り）

The stiffness on these is just right—cards slide in easily but stay protected, and the 200 count means I’m stocked for weeks of organizing my collection. I’ve even used them to mail a few trades without worrying about bends.

Finally, a sleeve that's rigid enough to keep my rare foils from bending in transit, yet thin enough that I can still fit them in a standard binder. The 200-count box means I won't run out mid-sorting session.

I’ve shipped about 40 cards in these and not one arrived bent—the semi-rigid stiffness really holds up in a bubble mailer. The 1/2” width fits standard cards snugly without any rattling, and the 200 count means I’m stocked for months.
