To the reviewer prior to me, this is a set of refills for the effect. The product heading states
that no instructions come with them.

Got my first refill and it was totally scratched up. Contacted Penguin customer service and they
were amazing and immediately sent me out another one. Unfortunately, the next one was also super
scratched up even though they shipped in a bubble mailer and were extra careful. Leads me to believe
they have a bad stock batch of refills.
A fun optical illusion I've been using since / The BLUR 2021 by Tenyo Magic /. There is an option on
YouTube.
I highly recommend it!
