Hi @elixirsoft! Elements has a monthly subscription fee (currently $29/month), with unlimited access to the items while you have an active subscription.
It’s worth noting that the licence requires you to specify the use of each item when you download it. If you want to use it multiple times, you can register a downloaded item for each end use. From the Elements site:
One Simple Commercial License
All items on Envato Elements have the same simple license terms. You get broad commercial rights, so you can use items with confidence on work or personal projects.
Register Items Each Time You Use Them
Each time you download an item, you get an ongoing license for a single, specified use. Want to use an item again? No problem! Visit your downloads and simply register it again for a different end use.
Clear Guidelines On What’s Not Allowed
Some common-sense limitations do apply. You can’t re-sell, re-distribute, use in on-demand services, or merchandise items without adding value.
