Hi,
are you making a Museum, too?
We have a K1 in the collection, unfortunately it is a single item and I cannot trade it.
Anyway, we have dozen of double items, so we can trade some readers with other not presents.
About the K1, if you receive offers, please note that the Museum is still looking for a K1 and K2 boxes to complete the readers.
Today the Museum counts 52 different readers, and day by day the collection increases
