Ento Sphinx, Black Enamel, Gold-Headed Insect PinsEnto Sphinx
From the Czech Republic.
Black Enamel, available in all sizes from 000 to 7 (and including 6A). With gold-coloured heads.
Size 6A pins are unique to Ento Sphinx. These pins are the same diameter as the regular size 6, but they are longer than the usual 6 at 45 mm.
Stainless steel pins are better for humid environments; this is a higher quality pin (which also means these are more expensive pins - no surprise!).
Gold-headed pins are the most common type of pins. The heads are visible but not "in your face" visible. These are excellent pins for a wide variety of specimens.

Size 7 pins are sometimes referred to as "railway spikes" because of their rather impressive size. They can be slightly more expensive than the little guys, depending on the supplier.
A word of caution: some display and storage cases may not accommodate the extra length of these "spikes". Most notably, size 7 pins are too long to fit California Academy drawers.
