Well, I’m in the states, so what you get in your part of the world could be different.
Look, it’s only a couple of 25-packs. Just buy the DVD-R and be done with it. You’re spending too much time on this and someone else could buy them. As long as you verify that they are Optodisc by the hub code and/or the dark grey spacer, you’re good.
There is no way to guarantee what design you’ll get, but if you don’t see the dancing dude on the DVD-R, then that probably means going with them will avoid that. The paper insert on the DVD+R is probably a clue that the design is on those discs. Unless you want to take a chance, just get the -R.
And packs of Optodisc will be made in Taiwan and have a dark grey spacer. In North America, the country of manufacture will pretty much always be on the label because of consumer protection and trade laws, but in your part of the world, it may not. It doesn’t matter anyway, since if you could see Optodisc hub codes, you already know what the DVD-R is. Just buy it before someone else does.
