This is a miniature version of our bowling ball briefcase. It is a fantastic way to hand out your business cards by making the magic happen right there on the spot! You show the flat briefcase-styled business card holder, and when you open it, out comes a large, solid acrylic ball! You can then remove the business cards to show that there is a solid bottom to the case! This will not only get you noticed when you meet a potential client, it will make sure you're remembered! This effect is manufactured to the highest standards to provide many years of magic!
