Bought these for my shoegoo tubes and they work great thread right on perfect and allow me to have extras to get into those tight spots inside spaces in the shoes. Generally (to save money) I take the one that I just finished using and clean it out when I’m done before the glue drys not perfectly but just to get the bulk out usually using a toothpick to clean out the tip is enough long as u make sure the holes not filled with glue your fine but u can also use a Qtip as well to clean out the inside a bit better if u wish. If you do this each tip will last u quite a while and give you many uses they’re pretty easy to clean and (atleast with the shoegoo) it doesn’t stick to horribly allowing reuse. So I’m satisfied……..also these are the same size and type tips that came with my shoegoo when I got it.
