PRO-Fit スモールデッキアウタースリーブカバー (60枚)

These are exactly what I needed to protect my pricier custom sleeves, and the fit is snug without being impossible to slide on. The clear plastic is also noticeably thicker than other outer sleeves I've tried, so I feel like the cards underneath are really safe.

I was worried these would be too tight for my deck, but they slide on smoothly without bending the card edges. The transparent film is crystal clear and doesn't add bulk, so my limited sleeves stay crisp.

Used these on my favorite limited sleeves and they fit like a glove, no sliding or bunching at the corners. The 60-count box lasted through two full decks with some to spare. Just enough thickness to keep the art safe without making the cards feel bulky in hand.
