These small glass bulbs feature a metal bas and a realistic filament. They have a hole drilled through the base for easy attachment on altered art, jewelry or display in Configurations.
Per Tim Holtz www.TimHoltz.typepad.com: - light bulbs - i guess you can say i had a bright idea? all jokes aside, these tiny light bulbs are great for collage work and even better, they already come with holes drilled through the base so you can hang them as charms or wrap with wire. it's just one of those random things i just had to have.
