Reindeer Lichen, Light green, (2) 11 oz. bags. Stays soft. If the air turns extremely dry it will become dry and hard; however, it returns to normal softness when the normal humidity returns. The treated reindeer lichen is non-toxic and flame retardant. Other uses include placement in tops of pots of dried and silk flower arrangements. It remains soft year-round unless exposed to continuous air-conditioning.
