The paschal trikirion in question (the one in the picture two posts above) is obviously slavic, as it has the slavonic lettering (may have been a gift from someone). That being said, the tradition of the single candle exists both in Slavic and Greek tradition and so does the Paschal Trikiri. There is also the tradition of intertwined (braided) 3 candles, 9 candles (3x3), 33 "side-stacked" candles, among other things under the sun. The point is that triple (of various designs), thick single, side stacked and braided candles are all used by all traditions. Among the Slavs Carpies tend to use single, Ukrainians and Russians triple. Romanians are various, some regions preferring one and some preferring the other. The Greeks have "all of the above." Some of the triple candle variety have stands others do not. Some have crosses attached others do not. As Bishop Jerome of ROCOR says, there are 33 ways of doing things in Orthodoxy and 33 ways of doing the 33 ways (maybe he said 17, but you get the point).
