Which brand is it??

They're Cattex giant mouse balloons. This color is "Standard Rose" (Looks pretty pink to me!) and I got a couple of clear ones, too. The dolls I got are also cattex. I'll take a picture of one when I blow one up, but I'm short on inflated balloon storage at the moment. As you can see, I have several large balloons inflated at the moment!

I see. I got some Cattex too, the 19" and the 32, but they don't inflate to the rated size by the manufacturer, the 19" inflates like 16" and the 32 (not sure if that's the size in inches) inflates like a 28"

I think it has to be the size in inches, but I reckon these oddly shaped balloons are a bit more finicky than a plain round would be. They also don't feel as thick as the latex in a Qualtex 18 or 24" balloon. I still very much like the mouse ones so far.

Yeah, they don't get very big, and you can see through them like the latex were very thin.... I am underinflating them 15% less the rated size to see if they last a big longer and don't pop prematurely

BTW, that pink colour looks cute, I guess one friend of mine would like a lot ^_^

I tend to gravitate toward pink (or "rose" or whatever heh heh,) red and clear balloons. This one's held up for about a week so far. I keep expecting it to randomly decide to pop, with that weak spot and all. Hasn't happened so far, though. I've been trying not to be too rough with it, for the same reason. I'd say I've more than got my couple-of-euros worth from it so far.

One 19" Cattex I used also had a weak spot, I didn't care about till the weak spot turned into a hole, it didn't pop but started to deflate slowly, I'm talking about the orange balloon in this pic: http://www.furaffinity.net/view/16969862/

I used rubber solution and a little squared piece of latex from a popped balloon, patched the hole, and inflated the balloon later. Didn't look very beautiful, but the balloon held for some days more till it popped, but the popping line didn't touch the area of the patch
