Ultima China Marker – Peel-Off Grease Pencil/Wax Pencil – Leaves Opaque, Easy to Remove Markings on all Glazed, Non-Porous & Polished Surfaces (Black)

These markers are a staple in my shop for marking wood, glass, metal, and acrylic plates. The wax is thick and opaque, so the lines actually show up on slick surfaces without skipping or smearing while I work. They hold up to the heat and handling in the shop, but once I'm done, the marks wipe right off without leaving a ghosted mess behind. It’s a straightforward tool that does exactly what it's supposed to do.

THESE PEEL-OFF GREASE PENCILS ARE ONLY DURABLE IF YOU KEEP THEM IN A DRY, COOL CLIMATE. A FOUR TO FIVE YEAR OLD CHILD CAN EASILY LEARN HOW TO USE THEM. HOWEVER, IT IS NOT WORTH THE PRICE. I FOUND AN EVEN CHEAPER BRAND FOR FOUR DOLLARS CHEAPER... YOU DO THE MATH! AMAZON CUSTOMER, PRIME MEMBER SINCE, 2015.

Break easier than I expected. However wonder for my projects. (Also I am a hard pressure writer so personally to blame for the breakage

These are great in theory, but they didn't mark all that well. We use them for marking leftovers & baking bins, but it often write so light that we can't even read what was written. They peel pretty easily, though.
