What's the big deal about these tips? The regular orange tip on the Elmer's bottle is adjustable to a very thin line or a line about a 1/4 wide. Shoot I've even used those red and yellow ketchup and mustard bottles to hold the glue because it was easier to fill them up from the big gallon jug. I've been doing the glueing for years with no special tips. Why spend the money when you don't need to.
