The Best of Both Worlds
Easy-closure SnooySeal
You needn't button it up one by one after the diaper change any longer! This game-changing design makes you can fasten the closure in one second!
How does it work?
It uses a hook-and-loop structure that gently interlocks to create its effect. It doesn’t rely on surface stickiness, glue, or fiber friction. Normal washing will not affect its function, and the fabric has been carefully tested for durability through many wash cycles.
Customized the Length
Grows With Them. The adjustable overlap ensures a perfect, secure fit around growing bellies.
A Little Care Goes a Long Way
The soft closure may occasionally pick up a little light lint. A lint roller or gentle brush can be used for easy cleaning. If needed, a lint roller or a gentle fabric brush can easily refresh it. For best care, we recommend keeping the closure closed when not in use.
