A sealed retailer Skyridge Blister, while you may not of seen this before it is an authentic sealed Skyridge Booster Pack accompanied with cards unknown to me as packaged by the retailer during 2003. 

The contents of the cards behind are unknown as well as the weight of the pack, and there is very little price information to go off this particular product and so ive priced it in that of a similar range of regular skyridge blisters

Feel free to contact me about anything, international buyers too : )
