Jupiter Used Trumpet instrument for band

Condition is very good/used. No dents. Valvues are stuck and probably needs to be fixed/oiled. I don't have much information since this instrument is my brother's. However, I do know that it has not been used for a really long time. It has also been thoroughly disinfected and stored properly. Unfortunately, I have to increase the price point because the prepaid label is only for 5lb. The weight of the product is 12lb but their prepaid label only covers 10 lbs for $22.50. Poshmark also takes a fee of $60 which was suppose to cover for shipping. I can also post the listing on ebay to avoid this fee, if you are interested let me know what you think.
