Access Control Exercise 3

Kilian is a luxury fragrance brand known for its high-quality, unique scents and packaging.

The NFT makes you a Kilian VIP member, and you get a yearly refill for the fragrance you own.

While Kilian is good at perfume making and marketing, let's say they could improve at smart contract development
