Also called butterfly envelopes.
Used for storage of many arthropods – not just butterflies!
For safe storage of specimens that have not been prepared. Glassine does not stick to the delicate tissues and does not leave a residue on the specimen.
Also popular with philatelists.

Available in six sizes.

For your convenience, we have made these available in smaller quantities (packages of 10 and 25), along with the more usual packages of 100.  Recognizing that some of you may find 100 envelopes to be an overwhelming quantity, especially if you are interested in more than one size of envelope.
