Good product, value is present but could use better packing
Size: 100 Hard Sleeves+100 Soft Sleeves
These were a great alternative for cards I was giving to a donation (not for money nor profit but still deserved protection). I forgot what the order was initially as everything comes in the one box; seems to be the original toploader box. I mention this because it is overstuffed and had tape around the entire box three times over; even then there were torn box corners. It didn't effect the top loaders as so far mine don't look scratched nor any more distorted than premium, known brands I've bought plenty of times. The penny sleeves weren't counted and I've only used a few but they didn't pop open on both ends nor were they oddly sized. I'd also say I didn't buy this for the gloves but mine only had one in it and tried it on just because and it fit pretty accurately- but I am a petite female with small hands so if you aren't (I wouldn't dare presume size nor gender demographics) but they'd be too small for someone who wears a men's or women's large or XL. Then again they could vary with purchase and I got lucky with size but unlucky with quantity. Overall this is the better value set I've seen and bought that has quality product and delivers on the provided claims; I would've preferred different packaging so I could order as a gift to send as well. Pictures to follow soon.

10% of Team Bags Don't Work!
Size: 1000 Hard Sleeves+1000 Soft Sleeves
(Since I wrote this review. The company made things right by sending me 100 cards leaves and 200 top loaders for free so they earned a 5 star)
10% of team bags had the glue peeled off when you removed the plastic cover, so they couldn't close. Besides that, everything else works well!

Highly recommend - Pokemon
Size: 500 Hard Sleeves+500 Soft Sleeves
Got these for my pokemon collection, everything was nice and sealed. Some of the hard card covers had some scuffs but it is what it is. Over all I’m beyond happy with my purchase. Quality is amazing, beautiful sleeves to help keep my collection safe. Thickness is great!! Easy to store and use. Love the extra gloves. I would highly recommend this products & seller. I’ve even been recommending it to my friends already. I will definitely be buying again. I couldn’t be happier.

Cell Phone Gadgets!
Model: AMAZON EXCLUSIVE Silver Swirl
These little attractive suction backs for your cell phone are really cool! My granddaughter got some for Christmas and I thought they were the neatest thing to keep your phone handy and near by! They attach without glue to the back side of your phone and are quite strong, not to mention cute! (because of all the colors you can buy!) When I'm making a recipe I can stick my phone to any smooth surface and its all in front of me. Or just cooking and talking to a friend, on facetime. Leave it to our grandkids to show us all the latest and coolest ideas!
