Frequently Asked Questions

How do I refill the ink when it runs out?

It's simple and mess-free! Just open the secure cap on the side of the roller, drop in 5-6 drops of the provided ink, and let it sit for about 2 minutes. The stamp will absorb the ink and be ready to roll clearly again.

Will the ink bleed through regular printer paper?

No. Our specialized quick-drying formula is designed to sit perfectly on standard notebook or printer paper without smudging or bleeding through to the other side.

What age group is this stamp best suited for?

This educational roller is perfect for preschoolers and primary school children (typically ages 4 to 9) who are currently learning and mastering basic arithmetic skills like addition and subtraction.

Ruined prom for my senior
Size: 3X-Large, Color: Bright Purple
• The seller's failure to cancel an order, despite promising to do so, resulted in the buyer ordering a replacement item and incurring extra costs. • Poor communication and unhelpful customer service from Amazon led to significant frustration and disappointment, impacting multiple important events. • The buyer will no longer use Amazon. Awful material EXTREMELY WRINKLED ill fitting. SAVE YOUR MONEY AND YOUR SANITY!!! DONT RECOMMENDED EVER!!!!

Perfect for Prom, the satin detail elevates the look
Size: Medium, Color: Black, Size: Medium, Color: Black
This sport jacket was a great item for prom. We had it altered and taken in a little to be more form fitting. It was lightweight enough to be comfortable and the color was a nice black with satin collar. It was a great value for the money and this is the second one I've bought. The first one was red for freshman homecoming. Fits true to size as this is a medium but we did want it a little more form-fitting.
