Ishihara Test by Liam Levanon

A great packet test

I love this packet trick. It's so easy to do, works every time and people know what it's meant to be without question. Can't wait to try it out on my optician next time I go!

Great great product!!! Shipped fast!

Absolutely Brilliant Packet Trick

Carry this around all the time, ready to go straight away when ever needed, and not one person so far has worked it out , leaves you fully examinable as well . Brilliant .
