Quality frame - turns a puzzle into art
Color: Black, Size: 19.7x27.6, Color: Black, Size: 19.7x27.6
This puzzle frame worked perfectly for my 50cm x 70cm puzzle—it fits exactly and really transforms the finished puzzle into a beautiful display piece. The frame is well constructed and has a clean, finished look that doesn’t come across as cheap plastic. Mounting the puzzle was very easy, and everything sat securely once in place.
It arrived well packaged with no damage, and the protective plastic sheet is a nice touch. It keeps the puzzle safe while being much lighter than glass, which makes hanging and handling easier.
Overall, this is a quality frame that makes your completed puzzle look like real wall art.

Superior construction & reasonable cost!
Color: Black, Size: 8x12
I had one old picture that was this odd size. I didn't want to spend a fortune, and this fit the price. When it came I was so impressed with the quality. Not glass, but I love the ease of construction with swinging tabs that held the back on instead of those cheap flat pegs you can't get back in the holes.. Excellant, superior. I love it! I hope it comes in more normal sizes as well, like 8x10, 11x14, 16x20 even!

Excellent solution at a great price point!!
Color: Black, Size: 5.5x8.5, Color: Black, Size: 5.5x8.5
Just received, opened package, and this is exactly what was needed. It fits certificates, documents perfectly. Needed the 8.5x5.5 size to fit a certificate and in prior years I had to to modify the document to fit a 5x7 frame (had no idea there was the perfect size available) and it was very low cost and very well made! The black frame has a soft texture which I love, and the Plexiglas material is rigid and not easily broken. It has numerous hanging or standing options.

Beautiful Non-Glass Frame
Color: Bronze, Size: 12x16
Love this frame!! I'm so in love with the new type of frame backing this one had! I hate those frames that have those tiny thin metal tabs that stick out where you have to bend up/down to remove backing but not this one! It has these really easy to use metal springs that you push down & turn & it easy pops out! Wish frames all came w actual glass! I thought this one had glass but was wrong, it has the thin plexiglass type covering where you remove the clear stickers from front/back. It will work but because I have it used in a bathroom, I will need to get a glass replacement eventually. Love the gold color, it's a really pretty gold, not overly yellow. Overall, I think its a nice frame & such a great value.
