I’ve been looking for comfy underwear that doesn’t cut circulation around the top of my legs. These knickers are super comfortable and also quite silky and smooth with cotton crotch for breathable comfort. Highly recommend.

Thankyou for a fab product. So happy to be able to give my daughter the opportunity to feel comfortable & safe when she gets her period.

My granddaughter loves these

I bought period undies and swimmer for my daughters. Great designs and they fit well. I was looking for very small size for my 11 years old. glad I found your products.Thank you very much ^^

I’m planning on giving the kit that includes two pairs of period undies, a washing bag, a waterproof travelling bag to place the undies in and heat packs to my granddaughter who is about to turn 11 years. The kit is well presented and the undies have some great designs on them. I’m sure she’ll be excited to receive the kit.

Love this!!!
It's comfy and it looks amazing!
It's actually not only extra large like the picture looks like.
I usually wear xxs or s, but it fits me!
Hoping the s or medium will still come back soon.

My daughter is very happy with her newest Nickerbot undies (her favourite brand). The pattern is very pretty, they are comfortable and provide good protection.

Great and I like the different prints you can buy

I have purchased for a granddaughter fir Christmas. Looking forward to seeing her in the bathing suit and not missing out on holiday swims. They seem perfect for school swimming classes also.

Excellent delivery time and great products for teens at the start of their period journey.
The swimwear is discrete in design and looks just like normal swimwear which was a big reason to purchase from MyNickerBot.

These are fantastic for the young ones just starting out.

Cute and does the job

Amazing fit, great product

Love the design and they are good quality thus far, only used for one period and they were great washed up a treat

Comfy and easy to wash undies really great quality thus far (only gone through one period so far)
