Ahhh don't know about the rainbows so I can't compare the GetAFixes to them BUT the GAFs were extreeeemely potent! Loooooved 'em! Hmmm now the picture..the ones I got had like an oldish mad scientist brewing up a batch with beakers, etc, colours used in the pic were blue, red, yellow and white.
The H2000 had (memory ain't the best, too much THC!) ahhh a girl on a bicycle with I think some mountain outline and 2000 on at the top of the tabs (depending if you got that section of the the sheet).
