Looking to purchase replacement weatherstripping for aluminum casement windows

Hi, I am a homeowner in New Hope, PA needing to replace some weatherstripping that has aged and is falling out of the grooves of my 20 year old aluminum casement windows. I bought the house used, so I don't know what brand of windows they are and no window repair company that has come to my home is able to tell me either.

I attached an image of the label that is affixed to the top inside of the window. That's the picture with the writing "Suncatchers Inc." at the top. The arm of the window that expands out when one cranks the window open says "Truth" on it. Someone thought that it might be a Marvin window based on that.

There are pictures of the material itself. There is a shot of the inside of the rounded, insulating part. It looks to me to be a black foam inside the tubing. It's about 1 cm high and the tubing part is about 0.5 cm thick or wide.

Do you have any material like this that I can try

Sincerely,
Joan

I thought that one might work, too, so I bought one package to experiment with, and it fit beautifully! I'll be buying more this week. It was easy to cut and work with. I also found the screen pins that fit my screens on your website. Mine had become brittle with age and would break apart every time I tried to remove my screens, so I basically stopped washing my windows out of fear. I had only been looking for 12 years in every hardware store I've come across for a matching pin! Just have to say, Swisco is awesome!
