Absolutely EXCELLENT customer service
Color: Green
This little guy is so freaking cute and is very well made. The squeak is loud but not overly so, and the construction is really sturdy. Itis stuffed well enough it can be thrown for an impromptu game of fetch. I imagine, if you are a dog, it would be fun to chew on all the different tentacles and drag all over the place.
I ordered it as a gift for my brother's pit bull, in the full knowledge it wouldn't survive the holidays, but hoping. Sadly, when it arrived it was so small! Definitely too small for such a big boy, and not even large enough for my kid's rottie/collie mix. So I did what you do in these situations: I initiated a return, stating my issue in the appropriate place
To my utter shock, an hour later I had been issued a full refund with the reason they listed being they had sent me the wrong item. I do not even have to send the toy back! I didn't ask for this; it didn't occur to me to even consider it. They just did it on their own. Which is why, despite the item I received being too small, made me want to run over here and leave a great review
To make sure the toy finds a loving home with a little woofer, we'll be donating it to one of the smaller local shelters. I'm sure it will be very happy with its new family

Larger and stick well
It's hard to find larger patches particularly ones that stick well. They work well for small, shallow wounds and stay on even where skin moves a lot like on the brows or shoulder.
Also because of the tapered edges, they are not very noticeable. I've never had any luck wearing makeup over any patches these included and suspect makeup works better over 8m ones, but I have managed to dot a little concealer over eyeshadow primer in the center of these patches with some success.

Work great. No irritation
I've tried several other brand and none work as well as Olive Youg at doing away with acne pimples. I highly recommend them

This is innovation
I occasionally get pimples that seem like asteroids hit my face and landed. I used to have those "cutting" patches to cover up for these large pimples but this product really saves the time wasted for cutting a size perfect for your asteroid. The biggest size was just enough to cover a large pimple I had recently (I would say the pimple was like 8~9mm measuring the longest size) and it did fine pulling out the sebum. Of course it wouldn't fit and stay on as a customized cut patch, but it definitely has the adhesion to do the job. The huge pimple was gone in around 2 days.
