These sticks are huge, much bigger in person than pictures make them appear (there's nothing in the pictures to compare by scale). They're about 4 inches long by 1.25 inches in diameter.
I bought these specifically for 3D printer bed adhesion and they are perfect for it. Not only did they resolve the slight warping I experienced, the color changing functionality is nice, it's basically purple when wet, so it goes on purple (until the layer dries) and it will turn purple again if re-wetted with water. This makes it handy to tell where you've applied it and when cleaning up, just rub a wet paper towel on it and it turns purple showing you where it needs to be removed.
The bed adhesion is actually TOO good, I can tell it makes a big difference to adhesion because the prints are far more difficult to remove than they used to be. Even my preferred technique of spraying rubbing alcohol as a release agent around the perimeter of the print, no longer works with this. I suspect the glue forms such a tight bond that the alcohol can't seep under. What I find works better with this is hot water soaked towel (or paper towel), wet the perimeter so the hot water dissolves the glue at the perimeter of the print, then slide floss under and work my way through until it detaches from bed.
After removing the print I find the glue has done nothing to damage the print itself. It washes off the print and the bed completely with water alone (I clean the bed with rubbing alcohol as well).
