I also use the school glue sticks and they wash out, are non-toxic and acid free, and hold very well temporarily. I get a supply at the beginning of the school year for $.50 each, never more than $1.00 each. I saw the Lapel Stick advertised on one site for $4.50 each--on sale, reg. $5.00 each. I'll stay with my glue stick which has the same qualities as the Lapel Stick for much less in price.
