I added one Merch (Patreon)

I added one Merch. It's a mug. Bros who subscribe to the $15 plan for 3 months in a row get it.
I want to do something for the lower plan as well. However, only stickers and posters were applied to the $10 and $5 plans.
The mug just has 'BAD BRO' written on it, so I think I can use it in everyday life, but I'm not sure about the stickers and posters.
Shall I add some simple nudes (not too explicit)?i
