This simple gadget may surprise you with how much additional contents it can recover from inside bottles of sauce etc. This has proven to be far more effective that trying to use an everyday kitchen utensil however it can be a bit messy... but will minimise waste and save money. The design has been made to be as universal as possible but may not work with all bottles (i.e. with an opening of less than 24mm and/or longer neck than 18mm. It should work with most common sizes... Refer to the images for Instructions for use and as follows: Get a plate or container you want to recover the contents of the bottle into/onto. Insert the Internal Scraper into the neck of the bottle you want to scrape out. Holding the small handle of the Internal Scraper that is protruding from under the bottle, push the scraper edge against the vertical inside edge of the bottle. Pull the bottle up so the scrapers lower edge will also wipe around the bottom inside surface of the bottle. While continuing to hold the small Internal Scraper handle, rotate the bottle counter clockwise. This only costs a few cents to print so will cover its cost within the first use or two. Even if you aren't worried about the potential to save money it can be of use when you want the sauce (or whatever is in the bottle concerned) and find it is empty and you don't have another one in the cupboard. With the Internal Scraper, chances are you will get out the amount you need at the time...
