Double precision burnishers (simple conical or tronquated shape)

Double-ended precision stone burnisher (one stone at each end). Choose two stones from the following combinations:

- agate or hematite,

- conical, pointed conical, flat tip, 1mm truncated, and 2mm truncated.

Conical tips are easy to use and versatile. For truncated shapes, the flat part of the truncated area allows for precise shading (1mm or 2mm truncated) and for creating white lines ("flat tip").

For curved shapes, choose single-ended tips.
