Sorry, I grew the Rainbow Marker, not the Permanent Marker.........but they are very similar. Below is the thread link if you want to give it a look. The main difference is the Sherbert's they used, RS11 (rainbow sherbet) vs. Sherbert BX. The Permanent Marker was Leafly's 2022 Strain of the Year. The other side is both Biscotti and Jealousy.
1st pic is Rainbow, 2nd is Purple......

But, anything "Marker" is going to smell like a black magic marker we all have used to label boxes and such. I was very happy with mine and it sold right out so others were happy with it too.
The original P. Marker was bred by Seed Junky's, and I see a lot of breeders offering the same exact strain. It's listed as mostly indica, but there's definitely some headiness to it, which I don't mind. Check my thread, the pic's are amazing towards the end. There are a lot of pheno's, some got quite tall while others stayed very short. But no difference in the smell, taste or effects.
