For the 3 for 2 offer use the coupon NOTES in the voucher code box on the cart screen.
 
Please note, this is only available for shipping within the UK as it contains matches. This is an envelope full of printed gags and gimmicks, rather than a set of lecture notes. A lot of fun to be had and some interesting magic ideas too.
 
Condition: Good, some wear and creasing to envelope and contents.
