Eduard's ProfiPAK series is their upgraded kits which come with aftermarket extras (canopy masks and photo-etch parts) as standard, so you don't have to buy the extras separately.
They were ordered twenty years ago directly from the manufacturer in the Czech Republic. Some, such as the Bristol F.2B, are no longer available. The kits are unopened (save one for photo purposes, as above) and in the original shipping box. All kits are in new condition; there is minor creasing to the corner of one box which did not affect the kit contents. The original purchase price of the assortment was $134 USD.
TERMS: You are welcome to inspect the kits prior to purchase. They are being sold as ONE LOT of six kits only, no individual kit sales. Due to downsizing the lot is being sold As Is, all sales are final, no refunds or returns. The price is firm (no haggling), accepted payment is cash only (no electronic payments or checks), local pickup only (no shipping). If you are reading this, then the items are still available.
I also have a number of other model kits, listed separately (see the link above).
