Perfect colors and sizes. It was my 1st time using balloon decorations. I bought 2 packs just in case I popped them...and I am glad I did because I did overfill some at first. Do not overfill them because they will pop. Only comment is that it only comes with a couple of the large dark purple and large glitter balloons, if there were a few more of each then it would be perfect. I had a few pink and blue balloons left over from 1st pack. I only opened the 2nd pack to get the dark purple and glitter balloons. (I Popped one of each from the 1st pack).
