"Funky" Glass Vase

"Funky" Glass Vase- approx. 6 & 1/4 tall by 4 & 1/2 wide. I love the iridescence of this "carnival" piece. Trying to id as I have not ever seen one with these "funky" indents before...the bottom isn't exactly smooth and there's a swirl pattern at bottom going on up to an overall swirl pattern. There is one area on a side that shows a "line" but that line doesn't go all the way from top to bottom as a molded seam would. Also, the indents aren't spaced evenly in that between 2 of them it's approx. 3 inches and on another side approx. 4 inches from one to the next. When the tool was used to created the indents, it appears it was not applied using same "pressure" on each as the bottoms of each indent while being rounded/domed at tip, they aren't the exact "height" of the tip one to the other. I am assuming the indents are there to accommodate/make carrying of the vase easier, or put here perhaps just to be "funky" and different? Wanting more info as to possible maker and even if other colors were made.
