Review on 📏 Functional Mini Retractable Tape Measure Keychains with Slide Lock - Set of 10 - Ideal for Birthday Party Favors and Everyday Use - 1m/3ft Tape Measure Length by Matthew Davenport

We used them as souvenirs at my son's 6th birthday party. He wanted a construction party and loves to play our big roulette wheel so it seemed perfect and it was! Our son loved them, each of the kids loved getting them, they were a hit. Here's what we weren't expecting - if you use them to play tug of war, for example, you'll cut your hands on the sides of the stretched tape. We've had a few bloody hands on kids because of the way they played with them OR because there was a disagreement about whose tape it was. Honestly, I wouldn't say it's the manufacturer's fault. This is more information for those who think the same way as we do. The prize is great but the roulettes are the quality of this prize. When used correctly, they are great. If used by 6 year old boys who are on a sugar rush from cake rush expect to get bonded once or twice. Own roulette is SO much. I doubt you will have problems with older or younger children.
