Review on TRENDBOX Pack Black 7Mmx200Mm Craftwork Crafting by Jessica Lewis

TLDR, not recommended for outdoor use in warmer climates. These glue sticks spread well and are very sticky when hot, but unfortunately once they cool down (after a few days) they harden into a hard, waxy solid and become too soft. I think. Something like black liquorice. On a mild summer day (80F) in the sunlight, the adhesive softens enough that it can be easily wiped clean (tested on a piece of cardboard). Being naturally black, it absorbs more heat in sunlight, but I still think it does. still unreasonably soft. Unfortunately, I only discovered this after ordering twice. I might protect my project with white card stock or vinyl to reflect the sunlight/heat.
