Is this enough to make a full set of rpg dice molds in small cups?

I ran out after 6 of the 7 dice. I used 4 oz cups and was barely able to make the six molds. The molds did turn out great, though!

How well does this retain fine details?

It does a great job with details.

What is the shelf life for parts A and B unmixed?

Hey mOWWck, the shelf life is about 1 year (usually slightly longer than that) if you do not use them. This is an approximate number and based on our experiences in keeping the products in our store. You should, however, place the products in a low humidity area to keep them longer. Do note that unused silicone last longer than unused resins before the products start gradually losing their properties (such as hardness etc.) Hope this helps and have a great day ahead!!
