Apologies for the slow response.
They are at a duty free shop in Labuan, a small tax free Malaysian island near Brunei.
Every stick in the shop from an open box is individually shrunk wrapper. I have never seem that before and it was a pain in the butt removing the wrap.
Malaysian seem to go for Cohiba and not much else. The shop is stocked with 2015-2017 box codes of HDM, Monte etc and some other really bizarre boxes like old HU and Cuaba LE's.
This seller has 2 suppliers that he sources from.
1 seems legitimate with all boxes having box codes/barcodes etc that all check out, the other supplier's bixes has many of the barcodes cut off, so for the Diplomaticos as I couldn't confirm the authenticity I didn't purchase.
Instead I went for the last few of his 3 packs of Trinidad Robusto Extra.
