Do you have trouble finding a female Combee? They are the only ones that can evolve into Vespiqueen.

I've attached a chart that shows the trading costs for various types of trades.

Here's how it works:
1) You buy as many Klefki as you would like to trade for.
2) We can discuss on a time when we are both online and available.

NOTE: The CP and IVs of Pokemon change when they are exchanged.
