Many inexpensive cues, especially imported cues, are built from ramin wood. Ramin wood is used as an alternative to the more expensive North American maple hardwood. It will feel lighter than a similar maple cue and has a tendency to have a yellowish hue to it. Following is a short description from www.kew.org

Ramin
Gonystylus species


"Ramin is the common trade name given to a number of light coloured tropical hardwood tree species native to the peat swamp forests of Brunei Darussalam, Fiji, Indonesia (Kalimantan and Sumatra), Malaysia (Peninsular Malaysia, Sabah, Sarawak), Singapore, Solomon Islands and The Philippines.

Ramin wood is prized for its fine grain and easy working qualities and the main products in trade are picture frames, pool cues, blinds, tool handles and decorative mouldings. The major importing countries are China, USA and Italy."
