Was dubious about buying, a bag, of the beeswift mp1 gloves, as I was actually looking for an alternate brand, I've had gloves before that were all bundled together, where the rubber was too hard and the material like an old rope, the company sent them out really fast delivery, individually wrapped, premium gloves, really happy, top drawer, as these will be stored in the garage, no damp or spider issues, big thanks to George @ gloves & stuff.

Decent gloves at a reasonable price. Delivered within a good delivery window. These gloves have reasonable longevity in medium workloads.

Good company to buy from; just took a bit longer than expected (9 days)from order to being despatched for delivery. The response was quick when I emailed them with a query. Will definitely use again.

C Cherie Rowdenvia Trustpilot

I've always had a good experience with this family run business, always able to ring and get any queries sorted. Quick delivery and products all as described on the website.
The process from order to delivery is smooth and stress free. I would definitely recommend them.

C Claire Davisvia Trustpilot

What an amazing company. I bought safety shoes from them and could not fault them with anything. Communication from the seller was spot on. Kept me updated on delivery times and delivery was super quick as well, not to mention that they had the best price out there. These shoes are so comfy :). Thank you very much, I would happily use them again and highly recommend to anyone. I am glad I did not cancel my order because of the previous bad reviews.

A pleasure to do business with George, Paul and the team. Have been using them for years and will continue to do so. Great customer service, speedy shipping and an extensive range of products.

Ordered some safety trainers as they offered the fastest delivery and lowest price. My order was a day late but this was due to a supply chain issue with the manufacturers. George kept me up to date and they still arrived before other company’s expected delivery date. The quality of the trainers are amazing and I will be definitely using this company again for my future supply’s.
