In Poland there is a very different view regarding varieties on Belgian stamps

Hello. I'm sorry my offer doesn't meet your expectations. I've tried to accurately present my stamps on the boards so you can examine them closely. 
If you feel you're wronged and dissatisfied, please return the stamps to me, and I'll refund your money and cover all shipping costs. If you'd like, please provide me with the full amount and your account number. I'll send you the money and wait for your shipment. I don't have any negative reviews, and I wouldn't want to. Best regards.
