Most of the time the 'large' Sugar skulls measure approx 17mm x 18mm--this guy 'Big Daddy' measures 25mm x 30mm. Notice in picture-- "baby" skull, 'Large"" skull for comparison. I have used clear glass crystals & large polymer Rose and wire wrapped it very secure. It will make an awesome keychain--or a great pendant on a necklace.
***(note--other skulls not included--just for picture purposes. I am including the key ring/clip.)
