/*

Highly Appreciated Fellows,

Welcome to the BluntBoys project!
Its our vision to create a rolling paper brand, with a strong based
community.
Subsequently are we testing borders, concerning other smoking
attributes.
Creating a ‘highly’ profitable future company, from which tokens
holders get interested is our goal.
Furthermore are we also planning to focus on NFT, and staking or
P2E.
Also check out our website https://www.bluntboys.net/ , or Telegram https://t.me/BluntBoysToken for additional info.

High regards,

HighDev
