 <p><strong>WARNING:</strong> Each time a user imports stickers, a <strong>new sticker pack</strong> is created on Telegram. <strong>Do not use</strong> the importing feature to share stickers you made with <em>other</em> users. If you want to share your stickers, simply upload them using <a href="https://t.me/stickers">@stickers</a> and share the <strong>link</strong> of your pack. For example, here&#39;s a link to install some <a href="https://t.me/addstickers/UtyaDuck">Duck Stickers</a>.</p>
