Hector Aguilar butterflies are 23 grams total and the large butterfly is 2.5 x 2.25 inches with the small on being 1 x 1.25 inches. These are crafted with thick silver and are properly hallmarked as shown one pre-eagle and the small one is an eagle 9 assigned to Aguilar along with his own mark. The butterflies are in working condition and the condition is supreme with no issues what so ever. These have an in flight flowing design on what ever you may attach them to. Wonderful set and a true treasure to have the pair. Due to restrictions on Trocadero I have no way to list both dates of the 2 butterflies.
