Are they peel seal? If not I would worry about them losing their stick over time.

Hi, unfortunately, they're not peel seal. I always use these envelopes and you're right they can dry out over a long period of time but it's only been the odd one or two. Not enough to stop me purchasing. Hope this helps.

Can you please tell the position of the window in the envelope.

Approximately 1.6 cms from left and 4.5 cms from top

How far up is the window from the bottom of the envelope and how far in from the left hand side?

the window measures 45mm high x 98mm wide and is 73mm up from the bottom and 15mm in from the left hand side
