The Miniature Book of Miniature Golf
The perfect gift for the bored golf aficionado.
This book is a complete, working 9-hole miniature golf course, with miniature golf balls and putter included.
You can get it cheap on Amazon (depending on who you buy it from). Of course, it would probably be easier to download a golfing game app for your smartphone, but at least it won’t drain your battery, or make your phone as hot as liquid magma.
