Nic Nac cookies are in Belgium well known for 'Sinterklaas' :) on the night from the 5th on the 6th of december Sinterklaas puts some of these cookies, other candy and toys in the shoes from the nice kids.
I thought it could be an original idea for a ring =)
I did some research and found that in other countries similar cookies are called 'ICED GEMS'
I used the term 'SECOND GLUE' I don't know if it's the right word:)
but what I mean is very strong glue that dries in seconds.
