Barrier Character Guard Flame Card Sleeves (60 Piece), Silver, 69 x 94mm

Will these fit over weiss schwarz character sleeves 67 by 92 mm?

Is the sleeve clear

Will a 60 card deck still fit in a standard ultra pro deck box after double sleeving using these?

Will these work to over sleave a pokemon deck? I want to put them over a sleeve so tge sleeves dont get all worn.
