Mint "block of 4" stamp swap : 5 qty

This is my first stint as swap co ordinator :-). Since I am an avid collector myself I thought this could be an idea that specialised collectors might be interested in.

Take 5 different mint block of 4 stamps and put them in a plastic bag. Two partners for each participant.

Must follow rules:

Please be sure to use moisture / water resistant packages to prevent damage to the mint stamps. No Definitives. Commemoratives only. No Used stamp. Should be in mint condition. preferably with tabs / margins.

The stamps may be from your own country and they may be as per availability. However reading the profile of your partner and choosing accordingly is always recommended. Try to use nice commemorative postage stamps on the envelope as well.
