Plastic necklace clasps

[TheLittleFriend]

Does anyone know where I might be able to buy plastic necklace clasps? I'm looking for the ones the snap apart when pulled, for a child's necklace. I can't find them online. Thanks

I'm a very good googler and I can't find any. Could you not use the magnetic ones which seem to proliferate at the moment. The magnets are strong these days....but not so strong that they're unsafe.

I'd not seen the magnetic ones, but they'll do the job, thanks!
