Businesses that are looking to stay compliant with Royal Mail’s Pricing in Proportion (PiP) guidelines, but also want to look at keeping their postage costs low, will find great use in the Royal Mail PiP boxes we have on offer at SR Mailing. These Royal Mail boxes are specifically designed to meet the ‘Large Letter’ requirements in a secure and professional package.

Available in a range of standard sizes, including C4, C5, C6, DL and Mini, our Royal Mail PiP boxes are made from durable 100% corrugated cardboard containing 70% recycled material. Fully biodegradable, compostable and recyclable, they’re ideal for any eco-conscious business seeking to reduce their environmental footprint. The boxes arrive flat-packed for convenient storage and can be quickly assembled when needed, perfect for busy fulfilment teams.

Each one of our Royal Mail PiP boxes comes with a highly secure adhesive strip that increases the overall security and will act as a tamper-evident system to give you and your customers extra peace of mind.

The very lightweight yet rigid design ensures your products will remain well protected in the various stages of transit, while also helping you qualify for the lower-cost Large Letter postage rate. Compared to mailing bags, these Royal Mail boxes offer a more professional and presentable packaging solution with enhanced protection against moisture and tearing.

Comfy but wear quickly
Size: Large, Color: Organic Cotton 2 (5 Black)
These are perfect for every-day wear and i find them super comfortable. Mine are starting to tear and fall apart, which is more quickly than my other underwear, but I think its worth it for the price and comfortableness. I'll just replace them or repair them :)

Soft and True to Size
Size: Medium, Color: Organic Cotton( 5* Multi)
Comfortable and true to size these boyshorts are perfect. It's great to know it's safe material and organic and it holds up well in the wash. I would definitely buy again.

Comfy cute undies
One of the first things I switched out when I went on my non toxic journey, I really feel like they help my hormones balance and they’re so comfy

Falls apart after 5 wash cycles
Terrible. Do not buy. Only last 5 wash cycles before unraveling and falling apart. Also, uncomfortable as hell.

Disappointing, durability despite softness
Size: X-Large, Color: Organic Cotton 2 (5 Black)
I really wanted to love these underwear. The material is incredibly soft and has a nice, thick feel that seemed promising at first. Unfortunately, the quality doesn’t hold up. After about 12 washes, the seams started coming apart, and within two months, I had to throw away two of the five pairs because the fabric separated from the waistband. It’s frustrating because they were so comfortable initially, but the poor stitching makes them a bad investment. I wouldn’t recommend these unless the company improves their durability or you’re OK with losing One or two pair of the five
