My daughter absolutely hated wearing these but I couldn't find any other way to get her to stop sucking her fingers! The guards to stop her from sucking her fingers were expensive and this was a cost effective method. My daughter had a difficult time going to the bathroom or cuddling with her stuffy. I think because of that, she stopped sucking her fingers within three days of using these. Review: Cute print, poor quality - Straps are very weak and were easily broken by the children when they tried to bend their arm and they leave marks on the arm since the strap material isn’t cushioned at all like the adult sizes are. Sadly I bought 2 sets wish I knew before our family trip they were such poor quality by the time we got back out return window closed. ## Features - Stop Finger Picking: you will receive 2 kids thumb sucking stops with adjustable straps for better arm fit and easy on and off; Not distinguishing between left and right hands, our children's elbow fixator is suitable for children under 7 years old and can be worn comfortably; It is recommended to wear two to prevent children from switching hands and sucking - Thumb Sucking Guard: our finger thumb sucking guard can effectively limit a child's elbow curvature beyond 45 degrees, keep away various hand contact habits, and is suitable for children with an elbow circumference of 4.5-8 inches; Stop thumb sucking within 5-21 days - Safe Material: our nail biting treatment for kids is designed with unicorn cartoon pattern, which is easier for children to accept; For friends who are troubled by their fingers sucking, this is a nice gift choice; The combination of quality cotton and a safe and soft lining is safe, skin friendly, and will not cause harm to the skin; It can be washed with water - Widely Applicable: the finger sucking deterrent can help children and young children stop sucking their thumb, biting their nails or pens, not collecting saliva, and maintaining good health; It only limits children's hand movements, such as eating and brushing their teeth, allowing them to play, write, and sleep freely; This is an ideal reminder - Professional and Effective: our finger sucking prevention measures about 7 x 7 x 5.8 inches in size, with a flexible design that helps you easily put on, take off, and adjust; Keep wearing it for 1-2 weeks, and you will see results; Effectively preventing children from putting their hands into their mouths without affecting daily activities ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CXDQS222 | | Age Range Description | Kid, Toddler | | Age range (description) | Kid, Toddler | | Best Sellers Rank | #127,685 in Health ( See Top 100 in Health ) #160 in Finger Cots | | Brand | Threlaco | | Brand Name | Threlaco | | Closure Type | Pull On | | Color | Unicorn | | Colour | Unicorn | | Customer Reviews | 3.8 out of 5 stars 171 Reviews | | Item Weight | 0.14 Kilograms | | Manufacturer | Threlaco | | Material | Cotton | | Number of Items | 2 | | Part Number | JYD-Threlaco-0640 | | Product Care Instructions | Hand Wash Only | | Special Features | Lightweight | | Target Use Body Part | Teeth | | Unit Count | 1.0 Count | | Unit count | 1.0 Count | | Use for | Teeth | ## Product Details - **Age range (description):** Kid, Toddler - **Brand:** Threlaco - **Colour:** Unicorn - **Material:** Cotton - **Use for:** Teeth ## Images ![Threlaco 2 Pack Thumb Sucking Stop for Kids Toddlers Nail Biting Treatment Finger Sucking Deterrent Guard Prevention Anti Nose Picking Pediatric Elbow Immobilizer for Boys Girls 2-8 Years (Unicorn) - Image 1](https://m.media-amazon.com/images/I/71Xq3wGtSOL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Effective and cheaper *by K***T on 20 May 2026* It worked!
