Spoiler:
This packaging seems quite robust for something that would more than likely be tossed in the bin.
Loads of extra stickers for labeling your keys.
Sweet keycap puller
I seen your post a while ago actually. I can't believe how clear your NOS IBM clear caps are. They always seems to have at least some slight yellowing to them so you must have been quite lucky to come across them. I actually have about 25 more on another Model M which look new but still aren't as crystal clear as yours. I suppose the ones I have in this box have not seen sunlight but possibly heat over the course of 30 years. Those Fenteks look very nice but to completely do up a 50 key Model M / F would be a bit expensive.
