Aegis Adhesives - 3" X 5" Red Do Not Open with Sharp Object Stickers (1 Roll, 500/Roll) Warning Labels with Permanent Adhesive

Labels are excellent quality and very easy to use. The print is bold and clear, color is vibrant, making the instructions highly visible during shipping. The adhesive holds securely to boxes, and the 500-count roll offers great value. A reliable choice for protecting packages in transit!

Fast delivery, perfect, eye-catching size. Just exactly what I was looking for.

We use these at work to put on boxes containing fabric material. They are bold, and stand out, and they stick well. We have never had an issue with them sticking to standard brown boxes. Quick ship!

Use on all my fragile shipping boxes that are sent out

It’s exactly what it says. Good quality and a fair price .

I bought these for a move to put on some boxes that were packed before the movers came, so they'd know which boxes were fragile, and which end of those boxes was "up." These absolutely do that. The only thing that could be better would be the adhesive. These were definitely not a "slap it on there and forget about it" situation. More times that I would have liked, I would apply a label, only to have it start peeling off when something brushed against it. These really needed to be pressed down thoroughly over their whole area to ensure they stayed put every time.

These are nice big stickers. They are very sticky too. The red is very vivid. I was packing my studio and a lot of wall art, frames and stretched canvases; these items have no structural integrity if they are horizontal and given the large surface area of any box, darn near impossible to protect unless you build a wooden crate. I needed some way to clearly mark the strong vertical orientation of these items and these sticker fit the bill perfectly. I don't know if the baggage monkeys will ignore them or not, but at least I have tried.

They look and work great
