      Choose your number of print colours

      Our mailing boxes come in white kraft and brown kraft. If you want to keep things simple and costs down then go with a one color designed mailing box. Feeling more adventurous or want a striking design then we offer full colour print, inside and out.

      Great service, went above and beyond to meet our launch deadlines. The tissue paper is excellent quality and would certainly use again.

      Jenny Middleton

      Great turnaround, super communicative & really affordable! Andrew & the team went above and beyond to meet our needs & expectations. Thank you!


      I was ordering boxes that look and feel lovely as they were for a commemorative gift for all pupils and staff in the school. The process was very simple, all contact was helpful and the end result is exactly what I hoped it would be. Highly recommend!

      Emily Wood

      I had such a great experience with Comet. With a super tight deadline - and working to a budget they exceeded my expectations. Robert kept me updated on progress and answered everything I needed to know. Couldn't recommend more

      Catherine Bethune

      I cannot recommend this company enough. Especially Gareth who I dealt with during my order, he was helpful, quick at replying to any questions I had and he just made the process so easy. His customer service is the best ive received. I had tissue paper branded with my logo and the end result is perfect, production and delivery was fast and the packaging was great too.


      Really good service from Comet, as others have mentioned they seemed super keen to make it work - from flexing the lead time to accommodating or order even though we were just off minimum value, they were super helpful. Gareth was very attentive through the whole process - chasing where he needed, checking colour matches. A great company to work with and the final products are great too! Will most definitely be using them again


      Robert from Comet packaging is incredibly helpful. I spent two weeks searching high and low for bespoke bags that could be produced within two weeks and a small quantity. From the moment that I spoke to Robert he was extremely professional and reassuring and very patient when it came to my many phone calls. I reiterated that I needed the bags by a certain date and they actually arrived 5 days early. I would highly recommend this company.


      Couldn't recommend Comet enough. We wanted bespoke gift boxes for our wedding favours and when we came across Robert he couldn't do enough to ensure they were exactly what we wanted. The quality is amazing and turn around time was fast. Will be returning in the future, Thank you
