Real or fake deca?

I recently bougt some norma deca. Comparing it to my friends, we noticed it was a little bit different. One was slightly shorter,with a light yellow tint. The other was clear.the letters were clearer on one of them than the other. nd the expiry date was stamped on (you could feel the imprint) while the other was printed on. Is one fake?

I’ve had both counterfeit and real Norma Deca recently. Brian Batcheldor’s recent article (issue 126) shows how to tell them apart (the square or round label corner is the easiest thing to spot - square cornered = counterfeit). I haven’t noticed much of a yellow colour though.

thanks Phil
