Yesterday I went to the Hypland x Yu-Gi-Oh! Pop Up, and it was terrific. The pop-up offered great merchandise, great displays, and overall amazing people.
I had an absolute blast meeting people talking about Yu-Gi-Oh! The pop-up had a photo booth and figures on display to which anyone could go.
The best part for me, though, was that with every purchase, they gave you a wristband, a deck of Yu-Gi-Oh! Cards and a Seto vs. Atem poster!
