The container is used to hold only the amount of glue to be used. It is used in combination with a metal spatula or toothpick. I recommend that the container be a moisturizing container with a hinged lid as shown on this page. An alternative tool is a yogurt cup, although it tends to dry out. Please refer to the website links for detailed features and prices.
