These packs are being sold as unweighed*. There is the possibility of containing a holofoil card. 
NOTE; THE BLASTOISE PACK CURRENTLY IN STOCK DOES HAVE SOME WEAR AT TEAR DUE TO AGE / THE WAY IT WAS STORED BY THE PREVIOUS OWNER. PACK IS SEALED. 
 
*Unweighed packs are generally sold if the set is difficult to differentiate between light and heavy weights due to inconsistent print runs.
