Idk it’s alright I guess. Kinda thin but it does the job. Giraffe face is a bit wonky on ours though.

The design is quite nice and the adhesive is strong enough for most plastic surfaces. However, the 'Pink' shade was a bit more muted in person than it appeared in the listing photos. It's a decent value for the quantity provided, but just be aware the color might not be an exact match for neon pink themes.

These are a must have in my gym bag now. I use them on my calves after leg day and they really take the edge off. No weird tingling, just numbs it out.

These are such a lifesaver for my old patio set. The stretch is real good and they actually stayed on during a windy storm last night.

These fit my Ridgid R213BNE perfectly! Honestly, for the price you can't beat it compared to what the hardware store wants for the OEM ones. No marks on my trim so far, so i'm happy.

They are okay. A bit thinner than I expected, almost like a heavy aluminum foil vibe but stronger obviously. They get the job done but they blow away if it's really windy out.
