-          A bulk NFT transfer utility made for transferring ERC-721 and ERC-1155 tokens between accounts easily.
+          A bulk NFT transfer utility made for transferring ERC-721 and ERC-1155 tokens between wallets very efficiently. 
+          <br />
+          Use it to vault your NFTs en masse or to distribute tokens to a large audience for some major gas savings. 
+          <br />
+          The higher the network gas price, the more savings you will see.
