These glue sticks are terrible. I have a Surebonder high temperature glue gun and these "clear" glue sticks have a yellowish tint to them. I've never had that with other glue sticks. They even look like they have a yellowish tint when placed on something completely white. Perhaps their color has changed over time as I don't recall that even in the original packaging they looked the same discolored when they arrived. The difference between these and other brands in the photo. I will throw these. Don't repeat the same mistake! Invest in better quality glue sticks.
