They look like a good pair of shorts.
If you want to have some fun at your family party, don't hesitate to buy these shorts; they only last a couple of minutes before breaking, but they are super fun.

The Ultimate Prank: Worked Perfectly and Completely Undetected!
I saw the viral dissolving swim trunks prank on Instagram and immediately knew I had to try it. I purchased these trunks specifically for my dad. Honestly, when they arrived, the quality looked kind of cheap to my eyes—but ironically, that worked in my favor! My dad liked the design so much he thought they were expensive and didn't want to get them wet for a whole hour! The perfect opportunity arose during a staged photoshoot for my mom's birthday. We all convinced him and my uncle to jump in for a "fun family shot." Mom made them jump in, and the look on their faces as the fabric started to go was priceless. It took about a minute for the thread to completely dissolve, giving us just enough time to snap a photo before chaos ensued. Great prank—they didn't suspect a thing! If you're looking for an unforgettable gag, buy these now.

Do it 😈
Epic. Beautiful. Wonderful. Best prank ever :) I think it’s the threads that dissolve, not the actual fabric, so it comes off in pieces.

Best Prank Of The Year
Best prank of the year! I couldn’t hold back my laughter! Even tho my husband thought this was hilarious he was really disappointed because he loved the swim trunks. He even asked if I could see them back together for him! lol. He’s 6’2 and weighs 225. He’s a 38 in the waist and an XL fit him perfectly. He loved the look and feel of them! They started to come apart within one minute and fully came apart at about 3 minutes. Highly recommend! Just make sure to have a towel handy for him or a backup pair of trunks! I’d love to try out different prank clothing from this company!!

I can’t wait for Summer!!!!
I bought these dissolving swimsuit a couple months ago. It took a while to arrive (1-2 months), but it is going to be so worth the wait when we finally go to beach (or river). My brother thinks that he is so cool and good looking. Even my parents believe it will be hilarious (my mom did say she will take an extra pair of shorts for him). I’m hoping that the second pair arrives before summer comes and he’ll have nothing but a towel. It’s making me laugh already. *My brother kind be quite the annoying little brother and gets away with A LOT because he’s “the baby”. He sometimes refers to himself as the baby and can’t be touched. I am so excited to see what happens 😁

Perfect Joke!!
I got these for my husband and friends as a gag gift for our trip to Belize. We tricked them into wearing them and when they got in the ocean, it took about 10 minutes for them to start desolving and their reaction was PRICELESS!!! These work and look great and they never knew by the material that it was a joke!!

Don't Buy!
They definitely did not dissolve. He was swimming in them in the ocean and the pool with no sign of dissolving. Don't buy these. Definitely dissapointed!!

Hilarious!
This was the perfect gift for my funny jokester husband! He likes to play jokes on others and didn’t see this one coming! While on vacation, I have him the trunks to wear to the pool where our friends were ( we were the only ones at the pool) it only took about 5 minutes when the trunks came apart and the material rose to the top of the water! Within a minute, the only thing left of the shorts was the drawstring! Worth every Penney for the laughs!
