I bought this item for my boss. It's a bit hard to buy so this item was an easy choice as it suited his quirky side! His outfit usually calls for a collar, so I knew it would be perfect. I tested the item to make sure it works. It comes with a few sheets of plastic that you can make yourself, but I've tried old gift cards and hotel keys. It was perfect! I love the idea of recycling items to make collars. This item is great for Father's Day, Birthdays, Weddings. Think groom gifts for business people! So unique!
