These thermal, polyethylene plant tags, rubbed off but may 

work for shipping purposes if the Industrial type is used. Some permanent pens that 

will work are the Sakura Identi-Pen, the Sakura Permapaque Opaque Pigment 

Marker and the black paint sticks, such as DecoColor available at Walmart. 

Besides the two Sakura marking pens, I also have a Sanford Uni-Paint opaque, 

oil-based paint marker listed. The Sakura pens, and possibly

other permanent markers are satisfactory for shipping and will last for at least

one season exposed to the weather. The black, oil-based paint sticks will last the 

longest outside but take longer to dry.

These thermal tags in the 7" x 3/4" size are less expensive than the 7" x 5/8" vinyl tags.

They are perforated and are easily separated. Color is white. The vinyl tags that are currently listed in this storefront are no longer being manufactured and are in limited supply.
