Smooth order, good shirt quality

I ordered a 'Don't Stop Believin'' unisex t-shirt and a 'World's Best Dog Mom' mug. The website was easy to navigate, and checkout was straightforward. Shipping took about 6 days to get to my home in Ohio, which felt reasonable. The t-shirt material is soft cotton, true to size, and the print quality seems durable after a couple of washes. The mug is a standard ceramic mug, dishwasher safe as advertised. I had a question about my order confirmation email, and customer support got back to me within 24 hours with a helpful response. Overall, a positive experience and I appreciate that they donate to charity.

Quick shipping, nice mug

Got a coffee mug with a quote for my sister. It arrived fast, like 4 days. Mug looked good, exactly as pictured. No issues with the order. Simple and easy.

Good value on sale

I was looking for a birthday gift and found Humans in Development. I signed up for their newsletter and got 10% off my first order, which was great. I also bundled a funny t-shirt with a novelty mug, and that saved a bit extra. Free shipping kicked in because my order was over $50, which is always a plus. The final price felt worth it for the quality and knowing part goes to a good cause. Definitely happy with the savings.

Mostly good, one small issue

I bought a couple of slogan tees and a sympathy gift for a friend. The t-shirts are comfortable, and the designs are well-printed. Delivery was about a week, which is okay, but I've had faster. My only minor gripe was that one of the shirts had a slight wrinkle in the print, though it smoothed out after washing. Customer service was polite when I asked about sizing before ordering. Good selection of heartfelt gifts.

Hey, thinking about grabbing a few t-shirts, but I'm always worried about sizing online. Are their shirts pretty true to size or should I size up?

L Leah J. 3 weeks ago
From my experience, they run pretty standard. I usually wear a medium and the one I got fit perfectly, not too tight or too baggy.

Yeah, I think they're true to size. I just ordered a couple for my husband and myself and we both got our usual sizes and they fit great. No need to size up afaik.

I'm thinking about getting a shirt for my dog, but is the quality good enough to last? My pup is kinda rough with his clothes lol.

The pet tees are actually pretty decent! My beagle wears his all the time and it's held up through a bunch of washes. No pilling or anything.

My cat (yes, my cat!) has one of their shirts and it's surprisingly durable. I think it'll hold up to a rough-and-tumble dog.

What's their return policy like? Just in case a gift doesn't work out.

M Matt Rivera 1 month ago
I had to return a mug once cause it arrived chipped. Process was pretty straightforward, just contacted them and they sorted it out quickly.

Returns were easy for me. I think you just need to initiate it within a certain number of days, but they're pretty good about it.

Are these guys legit? I like what they're doing with the charity stuff, but just wanna make sure it's not some scam.

N Nancy Gomez 1 week ago
Totally legit. I've ordered from them multiple times and everything's always been good. They donate a chunk to Destiny Rescue.

Yeah they're real! I actually looked them up before I bought my first shirt, they've been around for a bit and seem to genuinely care about the cause.

How long does shipping usually take to New York? Wanna get a mug for a friend's birthday next week.

E Eric S. 1 week ago
Mine took about 5-7 days to get to me in upstate NY. Might be quicker for NYC proper though.

I'm in Brooklyn, and my last order got here in 4 days. If you order soon you might make it.
