Greetings I would like to make a test order of 150/300units I would like to add a name tag/ logo to the product and add a logo sticker and barcode sticker to the bag (poly bag or zip lock bag if possible) Do you have the relevant certification for U.K./ sale on amazon? How long would this take to make? How much would this cost ddp to the U.K. by air? Thanks Regards David Show More
