Fabulous product

Honestly having a child (12) who has had her period for nearly 2 years it's heart breaking seeing her miss out when we are on holiday and making excuses to other family members why she isn't going in the pool, wuka has taken this stress away and made my daughter to feel like a child again when she is having her monthly's! Thank u for a fab product.
