Vinyl material, water resistant and perfect for your laptop, phone, yeti, car y mas <3 *Sticker orders are shipped as "letter mail" through USPS. This is the best way for me to send out your stickers at the best shipping price possible for you as a customer. USA orders are shipped via USPS and have an estimated delivery of 3-8 BUSINESS days (after processing period) depending on where you are located in the USA. Please note this does NOT include Weekends or Holidays. This is the estimate given by the USPS - SPC does not quote shipping times as the USPS often can take longer than quoted.
