It varies depending on the specimen, but safety first.
Many specimens will be removed the stands prior to shipping and a stand + putty is included with most specimens photographed on a stand.
For thumbnails, both glue and putty are or have been used (some items come out of old collections are are left in their original condition).
Contact us with any specific questions or requests.

Can I make an offer?

You are welcome to send offers, but typically we list items at their best price. Please keep in mind that sellers have a variety of expenses that are often not seen behind the scenes, such as: all associated fees and taxes, equipment, advertising, item cost, shipping (if applicable), etc. Thank you for your understanding!

What is the policy for refused and returned international shipments or unpaid customs fees?

We highly recommend not refusing your shipment or customs fees:
1. A refund will only be issued for the item once the shipment has been received by us, in its original condition. This is standard international practice.
2. Refused international mail is heavily delayed and commonly takes 4 to 12 weeks, with no return tracking information available.
3. If a carrier abandons or destroys the package, no refund will be issued. This is not something we have control over. Because there is no tracking on returns, we will not be notified if a shipment is abandoned/destroyed.
4. Original shipping is non-refundable. Any return shipping fees will be deducted from the final item refund.
