Just a few covers

Here are a few covers I came across while sorting through my collection. Happy collecting!

I'm Back!

Hello! I'm back from my three-week absence and, to start things off, here are some covers with recent Philippine issues.

These covers were actually sent by me to exchange partners and stamp dealers abroad, and I asked for them to be returned to me. Enjoy!

Sent to the United States

Sent to Thailand

Sent to Malaysia

Sent to Israel

This one, sent to Lithuania, is quite interesting because the cover was received in very bad order. The scan does not show it very clearly, but the cover was torn open on three sides and wrinkled! There is a stamp on the reverse which I take to explain that this cover was received in this order at the processing center in Vilnius. Who opened this letter and why they opened it is beyond me. May it have been a security measure? If so, why such brutal an opening of the envelope? Was the letter opened in the Philippines, along the way, or in Lithuania?
If only I could read Lithuanian, I would know what the backstamp says and perhaps the answer to my question....

Surprisingly, however, the contents arrive safe and intact according to my exchange partner.
