First NBL Mailday

Nice to see the old skool NBL cards mate, well done.

If you need any NBL inserts from 93-95, send me a PM
 
would it be better to leave them in their box or put them in sleeves?

Depends how much they are worth (to you most importantly), if boxed I'd have them in penny sleeves and toploaders, so leaving them in a sleeve would be better and easier also.
