My T1 came with plastic stylus with 1/8 inch diameter plastic tip.
I bought packet of cheap water color brushes with plastic handle. 10 for $5. Cut handle to 2 inch long. Can use handle or brush end as each works equally well. I like the brush end.
Soft handle end of interdetal brush as shown at this link and sold at local drug stores make good stylus. Link is only to show what I am talking about not a recommendation of product.

With practice finger works as good as any stylus except maybe when using on screen keyboard.
