Example Input: Purchased this two pack as I needed one bunny for each Grandsons basket! Only one grandson got a bunny the second was crushed to a blob! Used the one disposed of the other as it was too late too replace!
Example Output: 1

Example Input: So far I am really loving this product. I've used it twice since I got it and I haven't had to reapply yet. The only issue I had was that one of the bottle came with a cap and the other didn't. So it's hard to leave one at home and travel with the other one.
Example Output: 4

Example Input: Great small lightweight rotary tool. It is not going to be as powerful as a big one, but this thing is very handy and compact. The charging is convenient. You can use a USB phone charger or computer. It has standard connectors.
Example Output:
