[Coco] OT: Unknown cap type

[Salvador Garcia]

Hi all, I am making an almost futile attempt to do some Spring organization and found a couple of caps. I can't determine what type they are, for example electrolytic, tantalum , etc. (I pretty sure that it isn't any of the types mentioned in that list.)
Here is a pic of the mysterious cap:
