4-oz Kaplan waschbarer Schulkleber - 12er-Pack

The glue cap screwed off cleanly on all twelve bottles, no dried-up clogs at the tip. My kid spilled some on his shirt during art time and it came right out in the wash, which saved us from ruining a favorite tee.

These 4-ounce bottles are a good size for a classroom, and they dry clear on paper projects. The only drawback is that the tip can get a bit clogged if you don't wipe it clean after each use, but it's easy enough to clear.

The twelve bottles are a solid value for classroom or home use, and the glue itself is thick enough to hold paper projects without dripping. That said, the washable claim is only partly true for me—it came off my hands easily, but a dried spot on a cotton shirt needed a second scrub with soap.
