They work perfectly. They stick to the rule, rotate to remove the air and offer a perfect grip. Very happy with the purchase

Very comfortable thing!!! Plastic durable! The parcel came quickly. The seller recommends! the ruler holds well, firmly.

Very comfortable suction cups for lines, keep well. I liked the goods. Sent fast. The seller is good, I recommend.

Cool thing, took to the line. Sent and delivered very quickly. I did not communicate with the seller.

Excellent thing, thank you to the seller! Delivery of course is very long, it was more than a month!
