These glasses filled with mustard, are from Belgium brand "BISTER" and look like the ones from AMORA, but are not exactly the same.
In 2018 just these TWO were issued, see pictures.
One has the Smurfs Experience, 60 years Smurf logo.
Available types of glasses:
- A - Smurf with Atomium & Smurfette with cake (left on picture)
- NOT AVAILABLE ANYMORE
B - Smurf with autumn leaves & Smurf with umbrella (right on picture)
