I rather like my Tantus General, unfortunately, I see that "this item is discontinued". Holy cow, am I ever glad that I got mine when I did.
7 3/4" Length
6 3/4" Insertable length
O-ring compatible for a harness
After doing a web search I see that it is still available... from a surprisingly vanilla source, an online Drugstore. But it does look like Tantus has indeed discontinued The General.
