Easy to wear, washable, and suitable for both arms, it’s a practical, kid-friendly solution to promote healthier habits.

## Description

Features: Replace the thumb sucking habit with our finger sucking guard designed for 4.5-8 inches elbow circumference. Within 5-21 days, watch your child stop thumb sucking while the guard maintains their elbow curve under 45 degrees, keeping away from hand contact habits. Aid your children in breaking their thumb picking habits with our finger thumb guards. Leaving children free to play, write, and sleep. Ideal for preventing thumb sucking, nail biting, or pen biting. Specifications: Material: mainly sponge composite cloth and cotton Color: as the pictures shown Size: about 7 x 7 x 5.8 inches Package includes: 2 x Finger thumb sucking guard Notes: Manual measurement, please allow slight errors on size. The color may exist a slight difference due to different screen displays.

Review: Good concept, affordable price but my 5-year-old daughter can pull them down, so they’re not as effective as I had hoped ☹️ Also, she broke one of the clasps the first time she wore them.
Review: My 19 month daughter would not stop sucking her finger. I tried flavor nail polish, but no success. This is a simple and effective solution. It did take 2 days for her to stop fussing, but she eventually got use to it. 3 Velcro straps make it easy to use. Can't complain about the price.
