In my humble opinion the cards are on average in EXCELLENT/VERY GOOD condition, but please decide for yourself. These cards are really prone to damage so the quality is a bit all over the place! All cards are sleeved to keep them in this condition.
Pokémon Topsun cards are officially licensed Pokémon cards manufactured in 1997 by Japanese candy manufacturer Top-Seika packaged with Bubble Gum. These Pokemon cards had the first 150 Generation I Pokémon with their Pokédex numbers from #01 to #150 on them. The only Pokemon missing from Generation I is Mew.
These Topsun cards are just like the Carddass and Meiji ones seen as the original Pokemon cards predating the TCG game.
So these card sets started it all.
The Topsun cards come in 3 different versions, Blue back, Green back and a small 'prism' set.
This set consists of all 150 cards with a green backside!
See BULBAPEDIA (Pokemon wikipedia) for information about these Topsun sets. #1
