These come in multiple heights and can be adjusted to preferred diameter. The smaller ones work well when using 2 per toilet paper roll while the tall ones make colossal pillars when using paper towel rolls. Try a set of 8 on a map and you'd have a Parthenon entrance, repositioned they make a great hall, knock them over for some environmental effects. They work well when printing black & white too.

Simple, basic, can be used for multiple purposes. Work best if printed on full-sheet labels: print, cut to size, peel and stick! Couldn't be easier. This product is worthwhile, but I highly recommend the artist's videos which show additional, intereting ways to employ his products. Visit his YouTube channel for his videos. The link can be found on his homepage. Cheers!
