Enjoy the summer without these nuisances with these repellent patches. Simply slap these on your tent, baby strollers or desks and the specially treated seals will keep those bugs at bay to keep yourself bite free. Inside are 12 seals for you to use which lasts for a total of 6 hours. An officially licensed Sanrio product.
