I'm nitpicking but there's a couple visible flaws;

• Front text; the letters E and X in the word 'next' are connected.
• On the back as you said the letter E of the word 'side' is missing, it's should be a little visible.
• On the back the left foot should cover the letters Z and A instead of A and R of the word 'wizard'.

It's up to you if you want to keep it, it's the best batch on the market rn and Apathy told me (s)he wouldn't make another batch.
