WOW!! What beautiful and high quality balloons. I bought these to make a balloon arch and tested their stability and air holding ability two weeks before our event. WOW!! These really hold the air well. The color is true raspberry pink and gorgeous. I did not fill these all to the full 12" capacity, but regardless of how full or less I filled with air (merely blew them up by mouth) they held the size, color, and shape. These are beautiful balloons. Amazon price at the time was very affordable. This beautiful raspberry color goes perfect with fall colors: burgundy, golds, ivory, sage greens. Just use them interspersed for a beautiful look at any party. I have a few left of this color and will be looking forward to the next time I am able to add 'bright raspberry pink' to my decor. You will not be disappointed. Not one of the 6 or 7 I inflated popped or formed a white film on the outside, even after the two weeks. The smaller sized inflated ones I partially filled stayed inflated through the third week, and I was able to still gift them along with a present that long after my event. Great company. Great balloons.
