I purchased 2 of these and use them for everything. Use them to attach infant toys to stroller bars, baby gyms, infant bar handles, shopping cart covers etc.... When baby gets oldler they are great for teething and playing. Around 12 months of age, they can start linking them themselves for a great fine motor skill game. Then when they are toddling around, you can use them to link cabinets together to prevent babies from opening them. Such a cheap must have item. Highly recommend!!
