I'm confused about my new dildos

Never owned one before, got two for a great deal to try but I'm confused:

On the bottom of the packaging is says "This product is sold and should be used as an adult novelty only and should never be used other than for external use. It should not be used on a prolonged or frequent basis. It should not be used on swollen or inflamed areas or near or on skin lacerated or implied by the use of this product."

Is it safe to use in general? I thought dildos are meant to be used internally? I can't tell if this all is just for a legal disclaimer or not...
