I use the "Jumbo" ones because it takes less time to apply it to the bed.https://www.amazon.com/Elmers-E579-Disappearing-Purple-Sticks/dp/B00MZ5Q5QG/I found them locally. Target, Walmart, anywhere with school supplies most likely carries them.
The disappearing purple makes it a little easier to see where your glue coat might be missing some spots on the bed.
