Reddit mentions of Perfect Barrier Mini Card Sleeves (100 sleeves), 60mm x 87mm

The best thing to do would be to measure the cards yourself and find the closest sleeves that they would fit in. Card sleeves come in all sorts of sizes to accommodate a wide variety of board games and TCGs.

A quick google search suggested that the original 2004 Rouze cards were printed the same size as Bandai's Carddass product: 86 x 59mm. That means that any inner sleeve that fits Yu-Gi-Oh cards should also fit around Rouze cards. Here is an Amazon link that I found.

Again, your best bet would be to actually measure one of your cards and verify everything I just said.

Yo, I've pretty much went through a similar situation. I personally got the Ultra-Pro Pro-Tower, but there's probably better ones as I hadn't explored my options that much when I got it, along with the fact that I was new to everything. A few weeks later though, I wound up getting a lot more into collecting cards than I'd anticipated, which led me to getting binders. So ya, if you're sure you aren't going to get more than 130 cards or so, you might have to get another deck box for the few extra cards. Personally, I'd recommend getting something cheap since it would only contain about ~30 cards.

Also, to expand on what u/chimaeraUndying said, this would be the inner sleeve, and this would be the outer sleeve (Note the dimensions, and the fact that a yugioh card is 59mm by 86mm).

The cards themselves are to be sold for $24.50 (buyer pays PayPal fees):

  The cards are double sleeved in KMC Perfect Barrier Mini Card Sleeves (clear) and KMC Barrier Hyper Mini Card Sleeves. I can add them in for $6.50 (buyer pays PayPal fees).
  
  That's a subtotal of $31. According to this PayPal fee calculator, after PayPal fees, that would be $32.23 with sleeves or $25.54 without sleeves.
  
  I'll check conditions shortly, to see if I should reduce the price further.

I find that they work best with KMC Minis (62x89mm), as the perfect fits are 60x87mm. I also use the perfect fits with Konami sleeves which are slightly bigger and they seem to fit nicely. If Bushiroads/Enskys are any bigger than Konamis it'll definitely fit less snug.
