Mineral Tack by GeoFossils is the professional’s choice for safely securing mineral specimens, crystals, and fossils. While it may resemble ordinary poster tack, this specialised formula is chemically inert, non-hardening, non-greasy, and non-staining—leaving absolutely no residue behind.

Whether you're a museum curator, crystal collector, fossil enthusiast, or retailer, this unique display adhesive ensures your pieces stay in place while remaining fully protected. Perfect for both temporary setups and long-term display cases.

Sold in approximately 90–100g packages, this tack is highly economical:

• Mount 12–24 cabinet-sized specimens (fist-sized)

• 36–72 miniature specimens (golf ball-sized)

• Or up to hundreds of thumbnails

Usage will naturally vary depending on specimen shape, balance, and weight. It never expires, so stock up for future use—especially ideal when building or updating crystal grids, retail displays, or personal collections.

Works great on our customised display stands. See our range for specimen boxes!
