Five stickers on a wooden table. One is round, white with black letters that read "Big Tech, Big No". Another one is orange with golden letters on top, and says "Browser veteran". Third one is silver and has blue letters that say "Vivaldi inside", imitating the "intel inside" sticker. The two remaining ones are the Vivaldi logo on red, and on black with silver reflections.

I got myself the Analogue Pocket and own the Crystal edition since my childhood. The only thing that prevents me from playing it is swapping batteries, so savegames work.
