Certain items we carry, such as spirit gum and latex, are flammable and considered hazardous materials by the U.S. Department of Transportation. These flammable items are not permitted to travel on airplanes, and can only be shipped via UPS Ground. Since the U.S. Postal Service considers Priority Mail as air, flammable items cannot be shipped via USPS First Class, USPS Priority Mail or UPS Air. If any item in your order falls into this category then the shipping option for entire order is restricted to UPS Ground for domestic packages.

If your order is International, we are sorry that we cannot ship these restricted items to you. Please remove them from your cart to complete your order of remaining items.
