I wanted a safe bubble product for my year old cats. I researched the various "pet" bubbles and decided on this one based on product size, cost, and reviews.  I received in timely manner in a well packaged box with clear plastic covering the entire bottle.  Naturally I smelled the product and did detect a slight spicy scent but a bit of a cleaning product smell as well.  The bubble wand is standard as pictured.  The bubbles produced are sized from 1" to about 3" in diameter.  Just the right size for kitties to play with.  They last a substantial amount of time without bursting and do not leave behind any residue that I have detected.  I use them on an outside wood porch.  Compared to store brand bubbles these are a bit pricey but find these are some of the best bubbles I have ever purchased and worth the price. Also, the ad states the size is 4 oz. but the bottle states it is 5 oz.  I think this one bottle will last throughout the summer and fall season being used for a few minutes each day.  My kitties loved playing with these and sometimes required hitting the bubble a couple of times before they burst.  My one complaint is that this product is distributed by United Pet Group, Inc. in Ohio but the bottle states this product is made in China.  I consider this product worth the cost and would definitely make a repeat purchase but will research for a product made in the USA first.
