Size of a Feosol Original iron pill?

I have some of these listed for sale on amazon.com and a potential customer is asking for the actual dimensions of the tablets, I suppose so that she can determine how easy they are to swallow. I called their CS # and of course they couldn’t help. Anyone here have any and would be so kind as to measure one so I can post a reply? (Feosol Original, not the other types) TIA
