This brass-plated Yamaha trumpet, model number YTR200AD is a great student horn. I just played it for 30 minutes and all valves work well. The tuning tubes slide fine but could use a little grease. Bell is without a crease or dent. There is a small dent on the second valve tube. Mouthpiece is a Yamaha 11B4, also great for students. Case is a plain, grey. Yamaha, hard case. Price is firm, market price is $299 but this is discounted for the dent in the tube. Renting is fine, but purchasing a horn at this price for your student will start saving you money after just 13 months of renting a used horn (plus you can resell it one day). Thanks and let me know if you have any questions.
