Does what it says on the tin!
I bought these to use on some bamboo little lambs that are on loan from a friend. She gave me one of these fasteners to start me off and I decided to buy some more so I could have one in all the nappy changing places (table, changing bag, etc). They do the job without being too sharp if the baby accidentally rolls onto them (she didn't flinch) and are a subtle colour compared to others on the market. They also seem sturdy enough that they should last me until my baby is potty trained.
Thank you for your review, Hannah! ☺️
