A real ethically sourced butterfly wing is preserved in a borosilicate glass bottle, perfect for long-term viewing. Your choice of bottle size and closure. Corks can generally be removed with some effort. All other closures are permanently attached. Standard wings tend to be more muted tones, while premium wings are more colorful, patterned and/or metallic. Species availability changes rapidly. All wings come assorted based on current availability. Fantastic product information is included in an eco-friendly format that makes a tidy appearance and an interactive experience. A biodegradable straw is attached with a small leather band, and two scrolls of recycled cotton paper are artfully placed inside.
