The Sleeve Kings Difference

Who we are:

We are a small group of dedicated board gamers who happen to be passionate about one thing:  Card Sleeves.  Yes there are tons of card sleeve options out there but we wanted to create something new, a high-quality "standard" sleeve that was better than any other yet affordable.  We have been involved to some degree in sleeves for over 8 years and bring a unique know-how to this business.

Seth is the founder of Mayday Games, an established player in the board game and card sleeve space, and Jason is the brain child behind much of our sleeve development.  He handles the day-to-day factory operations.  Sleeve Kings is an all new kind of sleeve made in a different factory than Mayday and with a different process and different specifications, which is why a different company exists.  We are excited to bring these sleeves to the world!

The Sleeve Kings Difference:

So how are Sleeve Kings' sleeves different from the rest?

  • Thicker Than Any Other "Standard" Sleeves  -Most "Standard" Sleeves are 40 microns thick, a few are even 50 microns.  Ours are 60 microns thick! That is 50% more than most!
  • 10% More Sleeves Than The Other Guys -Standard sleeves come 100/pack.  We are the only brand offering 110 per pack!  10% more in every pack! 
  • The "Clear" Winner -Our sleeves are made from Cleartech™ Polypropylene.  Our sleeves are made from 60 micron thick sheets which are demonstrably clearer than the other guys.  You can actually SEE the difference.  Just as diamonds are rated on a clarity scale, even 100% polypropylene can vary significantly from product to product depending on how it is manufactured.  You will see the difference!

How obvious is the difference? The sleeve in the top of the photo above is FFG*.  The one below is Sleeve Kings with Cleartech™ Polypropylene. You be the judge.
*FFG is short for Fantasy Flight Games, a major player in the sleeve market.  Above is shown for comparison only, no infringement on FFG trademark is intended or implied.  

  • Cheaper Than Other Brands  -Most brands retail for $3 per pack or more for just 50 sleeves.  We are offering ours for $2-3 per pack for 110 sleeves, even for our largest sizes!. 
  • Buy Direct From The Manufacturer & Save!  -How are we able to offer these so cheap?  We ARE Sleeve Kings!  This is our brand!  We produce directly from the factory and sell directly to you.  There is no middleman!

    Please note since Mayday and Sleeve Kings have the same owner, we ship both Mayday and Sleeve Kings (Imperial Publishing) out from our same warehouse here in Greece.
