Cassette tapes from the 90s are now a collector's item, but keeping them in your cupboards no longer serves any purpose. This quick DIY method will help you flaunt these antiques in a useable manner.
Take four cassette tapes and using feviquick, stick the roller edge of one cassette to the top (opposite) edge of the other cassette to form a 90 degree angle. Connect the other two cassettes in similar fashion.
What you now have is a hollow structure with four cassettes making a block. Place it on a table and use it as a funky pen stand.
