Brightly colored, stick-and-go luggage labels from Ubrand are hardly a traveler’s must-have item. But they sure are fun.

The flexible-plastic, 3-D tags stick securely on suitcases and duffles and help airline passengers ID their bags on luggage carousels. The adhesive is designed to strengthen over time, and if you ever want to peel off the labels, they don’t leave a sticky residue.

I tested the monogram labels — my three initials in in black on white square blocks — on a suitcase that I checked on four different flights. Indeed, they remained on the bag through baggage handling. And when my daughter, who has the same initials, decided she wanted the monogram stickers for her own bag, we peeled them off with no damage to the bag.

Use UBrand tags not only to label luggage, but your kids’ sports bags, backpacks, musical instrument cases, camera cases or snow gear. They come in more than a dozen different styles — from the Hawaian hibiscus pictured above to a simple peace sign to a soccer ball.

UBrand tags cost $2.99 per monogram initial (less if you buy more than 2) and $3.95 for the other designs. Purchase them at UBrand.com.
