260K Mirror Silver Balloons Kalisan 50ct

There are two things that make Kalisan Mirror better than Sempertex Reflex: 1. If you've tried to compare Kalisan 260s with other brands (Sempertex, for example), you have probably noticed that Kalisan favors thicker latex for enhanced durability, while Sempertex has thinner latex to optimize for stretchiness. 2. Shiny balloons tend to just be more brittle than other styles. There's probably something about the reflective material that makes the latex weaker. So, because Kalisan optimizes for durability, the Kalisan Mirror line wins when compared to Sempertex's Reflex line. The colors and the metallic shine on them is nearly identical, but Sempertex's just pop way too easily. I rarely have problems with these ones, but I had one time where 4 silver Sempertex Reflex balloons popped in a row for the same kid.
